摘要
In this paper a special version of cooperative distributed space time coding for the relays network is proposed. According to this system model relays cooperatively collaborate with the sources to transmit the space time code to the destination. Process of the transmission consists of two phases. In the first time phase source broadcast the information to the destination and relay. In the next time phase, the source and relay cooperatively send signals to the destination by using an embedded space time coding. Structure of embedded space time code is based on singular value decomposition of circulant matrix. Relays are assumed to be non-regenerative amplify-and-forward. Theoretical analysis for calculating the bit error rate (BER) has been done based on maximum ratio combining (MRC). Simulation results for the case of one relay, one source and destination through the Rayleigh fading channel has been done and compared with the scenario when transmitter and relay used the Alamouti code.
