Abstract :
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 on the receiver side. We present a new channel estimation approach that does not require training data to estimate the unknown channel. We present an unassisted channel identifiability condition for space-time block codes. The algorithm is simple with low complexity. We also provide some simulation results.
