This paper deals with on-line Bayesian Cramer-Rao (BCRB) lo wer bound for complex gains dynamic estimation of time-varying multi-path Rayleigh channels. We propose three novel lower bounds for 4QAM OFDM systems in case of negligible channel variation wit hin one symbol, and assuming both channel delay and Doppler frequency related information. W e derive the true BCRB for data-aided (DA) context and, two closed-form expressions for non-data aide d (NDA) context. Index Terms Bayesian Cramer-Rao… CONTINUE READING
