A novel coordinated multi-point Joint Processing algorithm

It is well known that performance of MIMO system is greatly improved by used of spatial multiplexing and diversity. However, the performance of cell edge is dramatic depressed because of the inter-cell interference. This paper analysis the multi-cell coordinated transmission model and propose an JP(Joint Procession)-Multi-cell BD(Block Diagonalization) algorithm. Moreover, the different schedule strategies combing with the JP-Multi-cell BD algorithm are compared. The simulations show that the proposed transmission method can achieve the better performance than other method.
