Abstract :
This paper provides a comprehensive treatment of space-time blind minimum output energy (MOE) detection in multipath CDMA channels with receiver antenna arrays. Different constrained MOE detection schemes are derived using both the centralized and decentralized space-time receiver structures. Under each structure, the detection design is based on a generic constraint design framework that illustrates the tradeoffs between performance and computational complexity in a unified manner.
