Abstract: اتصالات الالياف البصرية هي العمود الفقري للبنية التحتية للاتصالات السلكية واللاسلكية التي تدعم شبكة الانترنت. النظام الاحادي الالياف المستخدم لنقل البينات لم يعد يلبي طلب الحصول على القدرة العالية والمتنامية بشكل مستمر. هناك العديد من الطرق الممكنة لزياد | Optical fiber communication system is considered as the backbone for the infrastructure of telecommunications that handles the internet. The exponentially growing capacity is no longer satisfied by using transmission of single mode fiber. There are several possible methods for increasing transmission capacity over fixed bandwidth. These include mix many signals with optical - carrier onto a one optical fiber by achieving various wavelengths, modulation employing different amplitude levels, and two orthogonal subcarriers and polarization. An extra dimension that a fiber can offer for achieving more information is space.This project demonstrates simulation systems for Space Division Multiplexing (SDM) transmission system using Few - Mode Fiber (FMF). Polarization division multiplexing (PDM) and Dense Wavelength Division Multiplexing (DWDM) techniques are also used in this system to increase total system data rate. For the ultra - high capacity need of SDM, Few Mode Fiber (FMF) was proposed as SDM best technology for obtaining ultra - high bit rate systems with long haul transmission. Inter - mode losses that appears in higher - order - modes was the most problem to be resolved. In this thesis, the description and design of three SDM systems were explored by using both QPSK and 16QAM modulation formats : single channel SDM system with PDM technique, 8 - DWDM channels over 7 modes SDM/PDM system, and 16 - DWDM channels over 10 modes SDM/PDM system proposed as future of ultra - high capacity optical system.By using 16QAM format and bit rate per channel of 40Gb/s, the maximum long reach of our designed single channel SDM/PDM system is 1020Km. A transmission reach of 760Km was achieved for 8 - WDM - 7modes - SDM/PDM system and 260 Km for 16DWDM - 10modes - SDM/PDM. At QPSK modulation format the maximum demonstrated reach was 1460 Km for single channel SDM/PDM system. A long - haul transmission of 1080 Km was recorded for 8 - WDM channels - 7modes - SDM/PDM system and 510 Km for 16 - DWDM channels - 10modes - SDM/PDM system.The total bit rate of single channel - 3modes SDM/PDM system was 240G/s at 40Gb/s bit rate per channel. The total bit rate was achieved by using 8 - DWDM channels - 7modes SDM/PDM system is 4.48 Tb/s at 40Gb/s. The highest bit rate was achieved by using 16DWDMchannels - 10modes SDM/PDM system so that the total achieved bit rate is nearly 12.8Tb/s.Chromatic Dispersion (CD) compensator using Digital Signal Processing (DSP) was proposed to compensate chromatic dispersion losses. Frequency and phase estimators were proposed in the designed systems to remove frequency offset and phase change by using Viterbi and Viterbi algorithms.Adaptive MIMO equalizer using constant modulus algorithms was proposed to compensate deferential group delay, polarization mode dispersion, and other losses simultaneously. Numerical results demonstrated that the methods are very effective in compensating the narrow band filtering and are very robust to channel estimation noise.The demonstrated systems were designed and tested by using (VPI transmission maker v.9.5) powerful software package.SDM techniques provided us with an important source to obtain more system flexibility, scalability, and capacity.

Abstract: استخدمت المضاعفات التناظرية على نطاق واسع في دوائر الاتصالات والشبكات العصبية ككاشفات للطور ومضاعفات للتردد ودوائر لمزج الاشارات والتضمين وفك التضمين. في التطبيقات التقليدية مثل دوائرالتضمين تعتبر ترددات التشغيل والسلوك الخطي للانظمة والمديات المسموح بها | Analog multipliers have been widely exploited in communication circuitries, phase detectors, neural networks, frequency multipliers, mixers, and modulation and demodulation circuits. In conventional applications, such as modulation circuits, the linearity, frequency of operation, and input voltage ranges are issues of great importance for multipliers. This work targeted these issues through the design of two types of four quadrant analog multipliers operating in wideband frequency ranges and having very high linearity with input and output voltage ranges of ±10V.The first wideband four - quadrant analog multiplier is designed using wideband squaring and operational amplifier (OPAMP) circuits. The wideband OPAMP is designed using 10 NMOS transistors based on 0.35 µm NMOS technology with supply voltages of ?12V. The wideband OPAMP has exhibited an open loop voltage gain of 3336545. The squaring circuit is built using two NMOS transistors and two wideband OPAMPs. The first wideband multiplier is built using two identical squaring circuits, two difference amplifiers, and one summing amplifier. It is characterized by high input - output linearity range of - 10 V to +10 V for both inputs, ±10 V input and output voltage ranges, and cutoff frequency of about 5 GHz. The second wideband four quadrant analog multiplier is designed using NPN bipolar junction transistors. It is built with two main circuits, which are the multiplier cell and the output circuit. The multiplier cell is built using a modified Gilbert multiplier, while the output circuit is a high gain circuit designed for changing the differential output of the multiplier cell to a single output having a voltage range of ±10 V. The multiplier circuit is designed with supply voltages of ?12 V. It is characterized by high input - output linearity range of - 10 V to +10 V for both inputs, ±10 V input and output voltage ranges, and cutoff frequency of about 1 GHz.Both multipliers are designed and tested on PSpice in ORCAD / Version 16.6.

Abstract: في هذا العمل, تم اقتراح خوارزميتين لتحسين اداء معيد الترميز التكراري التجميعي. الاول انجز باضافة رموز ارشاد بين سيل البيانات التي تدخل الى المرمز. في هذه الطريقة, رموزالارشاد ترمز مع البيانات المدخلة (رموز الارشاد المرمزه او الداخليه) مقارنة بالطريقة الاع | In this work, two algorithms were suggested in order to improve the performance of systematic RA decoding. The first one was accomplished by the insertion of pilot symbols between the data stream that entering the encoder. In this way the pilot symbols are encoded along with the input data (encoded or internal pilots) in contrast to the usual way where pilots are inserted after encoding (unencoded or external pilots). The positions where pilots should be inserted are chosen in such a way that to improve the minimum Hamming distance and/or to reduce the error coefficients of the code. Moreover, the known pilots have higher reliability than data and can significantly improve the initial decoding.The second proposed algorithm includes the utilization of the inserted pilots to estimate scaling (correction) factors. Two - dimensional (2D) correction system was suggested in order to enhance the performance of traditional Minimum - Sum (MS) decoding of regular RA codes. By calculating the mean square difference (MSD) between the values of received pilots and the a - posteriori data of bit and check node related to them, which are created by the MS decoder, an adaptive method can be achieved for getting the correction factors.Since encoded pilots in systematic RA code are embedded in data, it is possible to puncture all or part of them to increase the code rate. The pilots still have their effect on increasing the minimum Hamming distance.Extensive simulation tests reveal that the suggested quasi - optimal algorithms supply error performance be able to compare as Sum - Product (SP) decoding whilst maintain less complexity. Practical experiments are carried out by utilizing the capability of data acquisition toolbox supported by MATLAB to provide a hardware interface with the computer sound card. Here, the sound card plays the role of ADC and DAC converter in the physical layer. A different graphical user interfaces (GUI) are designed for the transmitting and receiving terminals to facilitate the selection of different code options. Signals are transmitted over wireless channel using a 2.4 GHz band indoor audio tranceiver. According to the aquired results, the modified coding system outperforms the original one when it is tested over AWGN and fading channels. An improvement may be realized about 1.5 dB and 1.3 dB at BER=?10?^( - 5) for punctured and unpunctured systematic (50,35,3,7) code with adaptive scaling, with three encoded pilots over AWGN channel and about 3.4 dB and 3.3 dB at BER=?10?^( - 4) for punctured and unpunctured systematic (50,35,3,7) code with constant scaling, with two encoded pilots over fading channel.
