In multi-user criteria, designed by pre-coding matrix can reduce interference between multiple users of the information, especially the use of relatively high complexity of the non-linear pre-coding algorithm, the most used algorithms such as THP (dirty paper coding algorithm), It achieved a compromise on the complexity and performance.
Key Technology
The information includes encoding and decoding two .m file by the sender using a reasonable pre-coding matrix design, at the receiving end by a reasonable solution pre-coding matrix designed to make the data between the individual cells within a multi-user flow is not interference because neighboring cell pilot multiplexing brought occur.
