Interference Suppressing for Cellular MIMO System

In this letter, we propose a soft/cancellation turbo equalization scheme to suppress cochannel interference(CCI) in space code systems. It is shown that the proposed method can effectively suppress CCI while preserving the space-time structure, without increasing receiver antenna, thereby significantly improving the system's interference suppression ability. The results of simulation express that the scheme can depress error bits rate when there is one or two CCI in the system.
