AbstractMultiple-Input, Multiple-Output (MIMO) communication systems promise to provide significantly higher data rates at no increase in transmitted power or bandwidth. Unfortunately it is challenging to locate space-time codes which achieve these gains. It was recently shown that codes based on Givens Rotation Matrices (GRM) out perform many of the more conventional space-time codes at extreme values of signal to noise ratio (SNR). This paper investigates the performance of GRM codes over a wider range of SNR, to determine their usefulness in MIMO applications of interest to the telemetry community.
