Abstract

This paper discusses wireless systems using antenna arrays at both the transmitter and receiver. Space-time coding exploits the parallelism of the radio channels formed. Theoretical results on signal-to-noise ratio (SNR) degradation due to imperfect pilot-based channel estimation are presented for Rayleigh fading environments. The analysis is also compared with simulation results
