Abstract: In this paper, pilot-assisted transmission over Gauss-Markov Rayleigh fadingchannels is considered. A simple scenario, where a single pilot signal istransmitted every T symbols and T-1 data symbols are transmitted in between thepilots, is studied. First, it is assumed that binary phase-shift keying (BPSK)modulation is employed at the transmitter. With this assumption, the trainingperiod, and data and training power allocation are jointly optimized bymaximizing an achievable rate expression. Achievable rates and energy-per-bitrequirements are computed using the optimal training parameters. Secondly, acapacity lower bound is obtained by considering the error in the estimate asanother source of additive Gaussian noise, and the training parameters areoptimized by maximizing this lower bound.
