Performance degradation of differential space-time modulation in fast frequency flat fading Rayleigh MIMO channels

Abstract

The performance degradation of differential unitary space-time modulation of any data rate, R, due to time selectivity is quantified for any number of transmit antennas, M, for fast frequency flat fading Rayleigh multiple-input multiple-output (MIMO) channels. The degradation bounds related to the Doppler fading parameter are tabulated and demonstrated for varying R, and M.
