Accurate estimation of MIMO frequency selective fading channels is important for reliable communication. In this paper, a new channel estimation scheme which relies on uncorrelated aperiodic complementary sets of sequences is proposed. Theoretical analysis and Monte-Carlo simulation show that the estimator achieves the minimum possible Cramer-Rao lower bound (CRLB). Furthermore, low-complexity algorithms for both ASIC/FPGA and DSP implementations are provided, using the special structure of the… CONTINUE READING
