This work concentrates on a MU MC framework where BD precoding is used for every cell premise. The MC framework under two working modes is analyzed: competition and coordination. Now in opposition mode, this work studies a key non-agreeable game, here every base-station insatiably decides its BD precoding methodology in conveyed way, in light of the information of the between cell obstruction at its associated versatile stations. By means of the game notion structure, the individuality and presence of NE in this SNG are thusly concentrated on. In the coordination mode, the BD pre-coders are mutually outlined over different BSs to enhance the system WSR.Since this WSR amplification issue is non-convex, so consider a distributed algorithm to acquire no less than a locally optimal solution. At long last, broaden the investigation of the MC BD precoding to the instance of BD-Dirty Paper Coding precoding. BDDPC precoding diversion for the MC framework in the opposition mode is been described and propose a calculation to mutually upgrade BD-DPC pre-coders for the MC framework in the coordination mode.
