Study of Adaptive Signal Selection Scheme for User Collaborated Reception

Abstract

User collaborated reception has been proposal method recently, which is for the multi user MIMO systems. In this ,mobile stations share their received signals with neighbors and process the signals. The precoding technique for Multi user MIMO is the conventional way to suppress inter-stream interference at BS side. On the other hand, User Collaborated reception is possible to suppress the interference at MS side. It is superior to the precoding when mobile terminals moves fast. Increasing users for user collaborated reception improve the performance of this system. Because it needs more resources for radio communication, the number of signals used for signal processing is limited. We proposed choose better signals for signal processing among collaborated users.
