Abstract
In this paper, we extend three equalizanon schemes proposed originally for conventional space-time block codes (STBC) [1]-[3] to cooperative schemes, carefully exploiting the underlying orthogonality of STBC. These three distributed schemes are named after their conventional counterparts as Distributed Time-Reversal (D-TR) STBC, Distributed Single-Carrier (D-SC) STBC and Distributed Orthogonal Frequency Division Multiplexed (D-OFDM) STBC. Considering the special case of single relay employment, our performance analysis for frequency-selective fading channels of memory L demonstrates that D-TR-STBC and D-SC-STBC schemes are able to achieve a maximum diversity order of 2(L+1) under the assumption of appropriate power control imposed on the relay terminal and high signal-to-noise ratio for source-to-relay link Extensive Monte-Carlo simulation results are further included to confirm the analytical results.
