Abstract :
In this paper, we investigate the use of OFDM to facilitate cooperation among relays in a wireless network. In particular, we consider different relay and subchannel assignment and combining schemes. Based on the amount of channel state information, resources, such as subchannels, can be allocated to relays to improve the end-to-end performance. Simulation results are provided to compare the performance of these schemes in terms of block error rate. It can be seen that significant performance gains can be obtained even with little channel state information at the relays.
