Abstract

The invention discloses a self-interference suppression hybrid precoding method based on orthogonal matching pursuit in a full-duplex millimeter wave two-way relay, comprising: obtaining a corresponding singular value decomposition matrix according to each channel state, and calculating a baseband precoding method according to the singular value decomposition matrix Coding matrix; Singular value decomposition is performed on the self-interference channel of the relay based on the baseband precoding matrix, and the left singular vector matrix corresponding to zero singular value is selected as the partial receiving precoding matrix; Singular value decomposition is performed on the self-interference channel of the node, and the right singular vector matrix corresponding to zero singular value is selected as a partial transmit precoding matrix; a complete precoding matrix is ​​designed by combining the receiving precoding matrix and the partial transmitting precoding matrix. This method utilizes the transmitting and receiving precoding matrix of each node under the mixed antenna structure of the millimeter wave system, and according to the preset coding sequence, realizes self-interference suppression for nodes and relays at both ends, and improves the spectral efficiency of the system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a self-interference suppression hybrid precoding method based on orthogonal matching pursuit in a full-duplex millimeter wave two-way relay, that is, a hybrid precoding algorithm based on orthogonal matching pursuit and null space projection. Background technique [0002] The millimeter-wave analog-digital hybrid precoding structure consists of two parts: a radio frequency phase shifter and a digital baseband, which can reduce system hardware complexity and cost. Through the design of analog and digital precoding, the suppression of full-duplex self-interference can be realized and the performance of the system can be effectively improved. [0003] Currently, research on precoding algorithms for full-duplex mmWave systems is very limited. Existing research mainly focuses on unidirectional relay systems, and only considers the self-interference suppression of relay...
