Blind Unique Identification of Alamouti Space-Time Coded Channel Via Signal Design and Transmission Technique

In this paper, we present a simple signal design and transmission technique to uniquely and blindly identify Alamouti space-time coded channels under both noise-free and complex Gaussian noise environments in which $p{\rm th}$-order and $q{\rm th}$-order statistics ($p$ and $q$ are co-prime) of the received signals are available. A closed-form solution to determine the channel coefficients is obtained by exploiting specific properties of the …
