Abstract :
Space-time trellis codes provide improved error performance for wireless systems using multiple transmit antennas. The authors have shown that such codes can provide full diversity gain as well as additional signal-to-noise ratio (SNR) advantage that they call the coding gain. Code design rules for achieving full diversity are also provided. Using these design rules, examples of codes, not optimal necessarily, with full diversity as well as some coding gain were constructed.
