摘要：
An innovations-based block-by-block maximum a posteriori fast fading channel estimation algorithm, based exclusively on the received samples of pilot symbols, is proposed. This algorithm enables the theoretical determination of the optimum positions of pilot symbols using the raw bit error rate criterion. Moreover it can be reformulated simply using appropriate weighting of the projections of received pilot symbols samples oil an extended orthonormal base. This base can be determined simply as a function of the statistical properties of the channel.
