Abstract

The invention, which relates to the field of communication technology, provides a hybrid pre-coding method of a multi-user system. Beam forming is carried out on a first layer of pre coded code and a transmitted beam of a base station points to a target user, so that the system energy efficiency can be improved; and a second layer of pre coded code is used for carrying out multi-user interference suppression. Therefore, two transmission problems in a system can be solved simultaneously by the hybrid pre-coding method.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-user system hybrid precoding method. Background technique [0002] Today, when spectrum resources are extremely scarce, large-scale MIMO technology, which improves spectrum utilization by continuously increasing the antenna size of each node, will undoubtedly become one of the key technologies of the fifth-generation mobile communication, and will have a great impact on the development of future wireless mobile communication systems. profound influence. The Massive MIMO system can realize wireless transmission by using multi-antenna technology at the transmitting end of the base station without increasing additional system bandwidth. On the one hand, the system can obtain space diversity gain through space-time coding, thereby improving link reliability and providing users with high-quality communication; on the other hand, through space multiplexing, the communic...
