Joint pre-coding and power control method for multi-antenna cellular network

The invention relates to a joint pre-coding and power control method for a multi-antenna cellular network, and belongs to the field of multi-antenna transmission of wireless mobile communication. The method is suitable for a multiple input single output cellular network, solves the problems that a cell edge user cannot be well scheduled and transmission efficiency is low in the conventional scheduling method and the problem of a relationship among performance, fairness and complexity, and comprises the following steps of: initializing, scheduling a cooperative user, scheduling a non-cooperative user and transmitting. Multi-point cooperative transmission technology and a channel correlation scheduling algorithm are adopted, and a transmitted signal is pre-coded, so that the performance andcomplexity of a system are well considered, interference among cells is effectively inhibited, the performance of the cell edge user is improved, and high system capacity can be achieved on the premise that the complexity is low and the transmission rate of the cell edge user is ensured.
