摘要: Space-time block coded transmission has established itself as an efficient means to enhance wireless communication performance over quasi-static fading channels. Its success relies on accurate channel knowledge the receiver side. We present a new estimation approach that does not require training data estimate unknown channel. unassisted identifiability condition for space-time codes. The algorithm is simple with low complexity. also provide some simulation results.
