Space‐time coding with receive combiner bank (STC‐RCB), in which a bank of receive combiners is added before the space‐time decoder for interference‐plus‐noise suppression, is proposed. Without loss of generality, the author consider space‐time block code (STBC) to be the representative of STC and study the performance for (STBC‐RCB). The author derive the output signal to interference‐plus‐noise ratio (SINR) (of the space‐time decoder) for STBC‐RCB under multi‐user cochannel interference. By regarding STBC as a special case of STBC‐RCB, the author also derive the output SINR for STBC under multi‐user cochannel interference. Simulation results show that the output SINR of STBC‐RCB can be much larger than that of STBC, also, they show that STBC‐RCB can adopt the appropriate receive combining strategy in the RCB to further improve the performance.
