Abstract:
This paper investigates the use of opportunistic Space Time codes with a decode and forward protocol in cooperative networks. CRC code is applied on the message at the source. At each relay, only the correctly received message block is retransmitted. We demonstrate that this cooperative protocol prevents propagation of error and optimizes the diversity order depending on the channel status and available transmit power.
