Title
Cooperative MIMO Relaying with Distributed Space-Time Block Codes
Abstract
In this paper, space-time block codes (STBCs), which gain from spatial transmit diversity, are applied in a distributed fash- ion at several cooperating relay stations (RSs) with multiple transmit antennas. It is well known that non-distributedSTBCs exhibit a degradedbit errorrate (BER) performancein spatially correlatedMIMOchannels. ApplyingdistributedSTBCs in co- operative relay networks reduces the probability of correlated channel coefficients as the RSs are spatially separated. In this paper, the Chernoff boundof the BER in Rayleigh fading chan- nels is extended to the case of correlated channel coefficients at the same relay station and different receive powers from dif- ferent cooperating RSs. It is shown that the BER performance has a higher sensitivity to spatial correlation in MIMO chan- nels than to different receive powers at the receiver from sev- eral cooperating RSs for distributed space-time coding. The theoretical results are confirmed by means of simulations.
