摘要
Abstract
A blind subspace frequency-domain channel estimation algorithm based on redundant precoding was proposed for single-carrier system with frequency-domain equalization and space-time block codes (STBC-SC-FDE) over fre-quency-selective fading channels. Blind channel identifiability was guaranteed up to one scalar ambiguity, and the resid-ual scalar ambiguity could be resolved. The proposed algorithm can estimate the channel impulse response of STBC-SC-FDE systems with redundant precoder only relying on the second-order statistics of the received frequen-cy-domain signal. Simulation results confirm the proposed algorithm is stable and reliable, and has high estimation and equalization performance.关键词
