摘要
In this paper, we propose an efficient channel feedback algorithm for network MIMO systems that selects the proper number of channels for feedback among the whole channels observed by each user and allocates unequal number of feedback bits to the users. The proposed algorithm considers a limited feedback scenario, in which the channel state information is conveyed from the user to the base station in the form of quantized vector index. Through computer simulations, it is confirmed that the proposed algorithm provides significant performance improvement over previously proposed schemes in terms of the average sum rate.
