Blind Adaptive Channel Estimation For Decoding of Orthogonal Space-Time Block Codes

In this paper, we provide a blind adaptive channel estimation method for decoding of orthogonal space-time block codes (OSTBC), which is built on the minimizing of an unconstrained cost function. The global minima of the cost function are analyzed. Both LMS and RLS algorithm realizations are given. Our method can adaptively track the time varying channel and decode transferred symbols without pilot symbols
