This book primarily intended for use by students in master's level and enhanced final-year undergraduate courses who are specialising in communication systems and wish to understand the principles and current practices of the wireless communication channel, specialty in An Outage Probability in Cooperative MIMO Under Slow Fading Channel , including both Alamouti STBC and Orthognal STBC. A new scheme for MIMO cooperative communication system under slow fading channel is presented.it is applied on Alamouti STBC, orthogonal and Qausi orthogonal STBC. MATLAB Simulation and numerical outage probability results demonstrate that the proposed cooperative MIMO scheme provides significantly minimizing in outage probability and increasing in diversity gains over both non-cooperation (SISO) and MIMO techniques.
