%X Layered space-time code(LSTC)proposed by Bell lAbs is mostly based on spatial multiplexing,its main object is to improve the system frequency efficiency.Yet a variety of space-time codes(STC),such as space-time block code(STBC)and space-time trellis code(STTC),are mostly based on transmit diversity.They predominantly take advantage of the gain produced by spatial diversity,including diversity gain and coding gain,to combat various fading of radio channel.This paper evaluates performance of several STC from the view of channel capacity,and at the same time,compares it with channel capacity of MIMO with the same transmit and receive antenna number.
