Cooperative diversity has been proposed to enhance the performance of high-rate communications over wireless channels. It realizes spatial diversity advantages in a distributed manner where two or more nodes share their antennas to mimic a virtual antenna array. The current research on cooperative diversity assumes the availability of perfect channel state information at the receiver. However, in practice, the fading channel coefficients need to be first estimated and then can be used in the detection process. This book first presents a comparative performance evaluation of cascaded channel...
