Реферат: A binary design criteria for PSK-modulated space-time codes is provided. For linear binary PSK(BPSK) codes and quadrature PSK (QPSK) codes the 'binary rank criterion' (i.e. the binary projections of the unmodulated code word, as binary matrices over the binary field) is used as a design criterion. Fundamental code constructions for both quasi-static and time-varying channels are provided.
