Interference cancellation and BER improvement in a wireless network using Network MIMO

This paper outlines the current state of Network MIMO as a viable technique for increasing the performance of wireless communication systems by cancelling the intercell interference in the near future. It also presents the results of a simulation environment designed to compare the BER performance capabilities of a wireless multiuser OFDM systems with and without the use of Network MIMO. Simulations confirm that Network MIMO techniques can result in significant reductions in interference. “Network MIMO” is a family of techniques where each user in a wireless system is served through all the access points within its range of influence. Taking prior information theoretic analyses of MIMO to the next level, this report quantify the spectral efficiency gains obtainable under realistic propagation and operational conditions. The results confirm that Network MIMO stands to provide a multiple fold increase in spectral efficiency by cancelling intercell interference and reducing Bit-Error-Rate under such conditions.
