摘要：
By exploiting diversity techniques, the information capacity of communications systems can be significantly increased. Research has recently been focused on a set of codes that introduce spatial and temporal correlation into signals transmitted from multiple antennas to provide diversity and coding gain at the receiver. Such codes are called space-time codes. The paper provides an overview of various space-time coding techniques, which include space-time trellis coding, space-time block coding, concatenated space-time coding, differential space-time coding, space-frequency coding and layered space-time codes. We present some of the latest research in these topics, in addition to presenting some design criteria and example codes.
