The invention discloses a hybrid beam forming method based on grouping optimization. An existing method cannot well reduce inter-user interference, so that the system sum rate is not high, and good availability is not achieved. According to the method, the users are grouped by utilizing the user correlation and the user correlation threshold, the users with high correlation are divided into one group, and meanwhile, the number of the users in the group is reduced. Then, a vector set capable of providing higher signal power is screened out by utilizing the correlation between the user channel vector and the codebook.

In order to maximize the capacity, a low-dimensional exhaustion algorithm is used in the group to reduce inter-user interference. And a greedy algorithm is used between groups, so that the influence of grouping is minimized. And the interference is greatly reduced while the system and the rate are improved. The method provided by the invention can effectively reduce the interference among users and improve the system and rate.
