Space-Time Coding for Single Carrier Block CDMA Systems

Abstract

—In this work we propose a unified framework for single carrier space-time CDMA block transmission systems with Alamouti’s code. The proposed system uses the multiantenna and multipath components as redundant information to produce schemes with full diversity gain, G d = n T L , where n T is the number of antennas and L is the number of multipath components in the transmission. The proposed system allow us to exploit the orthogonal property of Alamouti’s code and to decode each transmit symbol separately, thus, reducing the computational complexity.
