摘要：
This invention presents methods for using spatial FFT to reduce the number of computations for generating the pre-coding matrix in a MIMO system comprising reducing the dimension of channel vectors by neglecting entries whose values are significantly smaller or near zero, and to select UEs into a group assigned to the same time and frequency resources.
