Abstract :
We consider a multi-antenna system using space- time trellis codes (STTC) over independent, non-identically distributed, rapid, Rayleigh fading channels with pilot-symbol- assisted-modulation channel estimation. The maximum likelihood (ML) receiver structure that incorporates the imperfect channel state information (CSI) from the pilot channel measurements, is derived. The exact pairwise error probability (PEP) and PEP bounds for the ML receiver are obtained. Using the explicit PEP bounds obtained, a new pilot power allocation scheme is proposed to improve the performance of STTC at no additional cost of bandwidth or power.
