Abstract

Time reversal (TR) space time block coding (STBC) is a novel time domain technique to mitigate inter-symbol interference (ISI) in frequency-selective fading channels. This paper derives time-domain TR equations without requiring the q-operator, and presents simulation results for the case when channel estimates are not accurately determined through training. The time-domain TR equations have particular relevance towards the architecture of a TR-STBC system implementation whilst the calculated effects of channel model inaccuracy impact system packet structure and protocol issues.
