[C09] H. J. Yang and J. Chun, “Zero-forcing-based two-phase relaying with multiple mobile stations,” in Proceedings on IEEE Asilomar Conference on Signals, Systems, and Computers, Pacific Groove, CA, Oct. 2008, pp. 351-355. Abstract It is well known that relay stations improve the link performance between the base and mobile stations and thereby improve the total system throughput. Nonetheless,… Continue reading
