This technique is mainly designed to combat channel fading in downlink transmission by combining the technique of channel coding and that of array diversity, hence increasing the capacity of wireless communications systems and giving diversity gain and coding gain to them. It can also improve the bandwidth efficiency of traditional single-antenna systems. This technique is intended to provide new solutions to the problem of limited bandwidth. Space-time coding(STC) technology has better spectral efficiency and better communication quality. It can satisfy the need of high speed data communication services. STC technology can divid into: Layered space-time coding (LSTC), space-time trellis code modulation (ST TCM), Unitary space-time coding (USTC), differential space-time coding (DSTC). This thesis is mainly focused on the space-time coding technique by combining array signal processing. Firstly, we introduce the principle of space-time code and give the design criteria of it for quasi-static flat-fading channels. Secondly, we classify spa
