In this paper, we consider the problem of cell edge users inter-cell interference cancelation by means of precoding transmission when both end users and Base stations are equipped with multiple antennas. Simple precoding algorithm for downlink multi-user multi-cell multiple input multiple output (MU-MIMO) systems is introduced. The proposed algorithm maximizes what is called per-antenna signal to leakage plus noise ratio (PA-SLNR) performance criteria and make use of multi-cell spatial diversity to enhance the performance of the cell edge user in the Multi-cell Processing(MCP) scenario. Bit error rate (BER) and output SINR outage performance metrics were used to evaluate the performance of the proposed method. Simulations result shows that the proposed PA - SLNR precoding for MCP outperforms the conversional liner precoding methods.
