摘要：
Space-Time Coded Block Spread (DMA (STC BS-CDMA) was previously proposed to enhance the advantages offered by (DMA system with block processing. However, STC BS-CDMA suffers from long decoding delay and large single block transmission time which makes it unsuitable for communication systems delivering delay-critical applications and poor performance in systems with high mobility conditions. This paper proposes Space-Frequency Coded BS-CDMA (SFC BS-CDMA) which performs space-frequency coding instead of space-time encoding. This reduces the decoding delay significantly and transmission time of a single block, making it an attractive alternative in delay-critical communication systems. This paper also compares the two MIMO BS-CDMA systems and provides extensive simulation results.
