Combined-coding Effects over Multiple Access Transmissions
نویسندگان
چکیده
Coding/decoding techniques represent important error correction methods in multiple access transmissions which ensure reliable communications. This paper aims to evaluate the results obtained by combining of two relevant techniques (convolutional and LDPC), analyzing their joint effects based on the BER performances. Multiple access transmission is achieved with different types of signature sequences and based on their correlation degrees the performances of the transmissions are highlighted. The signals are affected by AWGN and the efficiency of combined coding/decoding techniques is reflected in improved BER as SNR increases. Based on the achieved results multiple conclusions are outlined in the final chapter.

Network Coding Applications for 5G Millimeter-Wave Communications
The millimeter-wave bands have been attracting significant interest as a means to achieve major improvements in data rates and network efficiencies. One significant limitation for use of the millimeter-wave bands for cellular communication is that the communication suffers from much higher pathloss compared to the microwave bands. Millimeter-wave links have also been shown to change rapidly, ca...
متن کاملPerformance Analysis of Several Quasi-orthogonal Codes Optical Cdma for Radio-over-fiber System
An optical code-division multiple-access (OCDMA) network for radio-over-fiber (RoF) transmissions was proposed. The network encoders/decoders (codecs) were structured based on arrayed-waveguide-grating (AWG) routers coded using modified prime codes (MPCs). In the proposed system, the lower in-phase cross correlation could reduce the beating noise, and in the proposed study, its performance was ...

Mitigation of multipath fading effects and suppression of multiuser interference (MUI) constitute major challenges in the design of wide-band third-generation wireless mobile systems. Space–time (ST) coding offers an effective transmit-antenna diversity technique to combat fading, but most existing ST coding schemes assume flat fading channels that may not be valid for wide-band communications....
