Coded cooperation using Reed Solomon codes in slow fading channel

Abstract

The coded cooperative communication technique utilizes single antenna mobiles in a multi-user environment that share their antennas and incorporate channel coding schemes in order to achieve transmit diversity. This letter presents a new coded cooperation system based on Reed Solomon codes. The RS codes are very effective in correcting random symbol errors and random burst errors over fading channels. The new coded cooperation system splits the data into two frames, using a vector arithmetic operation. The performance of the new system as compared to the coded cooperation system that utilizes the Rate-Compatible Punctured Convolutional (RCPC) coded cooperation is significantly superior with improvement for full diversity gain is around 10dB under variety slow fading channel conditions.
