Abstract :
In this paper, with the purpose to exploit the space and the frequency diversity, we propose an amplify-and-forward (AAF) cooperative system using orthogonal frequency division multiplexing (OFDM) with space-frequency codes (SFC). The signal processing algorithm of this presented system is introduced in detail and we also provide the system optimal power allocation strategy. Simulation results prove that SFC based AAF cooperative system can have better performance compares with SFC based DAF system and the optimal power allocation is efficient in both SFC based AAF and DAF cooperative systems.
