Abstract :
Distributed space-time coding (STC) gives rise to nonidentical channels between different transmit and receive antennas, which are not co-located. Therefore, the performance and the optimum power allocation strategy for distributed STC is different from conventional STC. In this paper, we derive the exact bit error probability for distributed space-time block codes over nonidentical Ricean channels, with an arbitrary number of relays. Based on the closed-form BEP results, we investigate the optimum power allocation strategies between different nodes and symbols.
