In the last few years, several works have investigated the performance of cooperative wireless systems with
various types of channel codes such as Low Density Parity Check (LDPC), Turbo, CRC, convolutional and recently Reed
Solomon (RS) codes. These cooperative schemes give power to single antenna mobiles to originate virtual multiple antennas
transmitter, MIMO system, by sharing their antennas so that diversity gain is achieved. The most common cooperative
schemes are decode and forward (DF) and coded cooperation (CC). Concatenated Reed Solomon and convolutional codes
have been used by several wireless communication standards like digital video broadcasting (DVB) standards and IEEE
802.16e WiMAX standard. In this paper, we develop two different coded cooperation schemes and apply them to the
mandatory structure of physical layer specifications of IEEE 802.16e WiMAX. The results attained for both coded cooperation
schemes present magnificent diversity gains over non-cooperative scheme.
