摘要：
The performance of space-time block and trellis codes proposed for narrowband systems is evaluated in wideband code division multiple access (CDMA) system operating over a frequency-selective Rayleigh Fading channel. The evaluation is done by both analysis and computer simulations. The considered space-time codes are shown to provide considerable performance improvement over uncoded single-antenna transmission at high signal-to-interference-plus-noise ratio (SINR), but at high system loads the performance is pronouncedly limited in frequency-selective channels due to increased interference.
