Abstract

The invention discloses a device and method suitable for separated type asymmetric hybrid beam formation in a high-frequency-band multiple input multiple output communication system. A transmitter adopts separated digital analog hybrid beam formation, data flow is mapped to different radio frequency links through digital precoding, each radio frequency link adopts a different phase shifter processing module to realize analog beam formation of the radio frequency link, and an array gain of a phased antenna array is utilized to resist channel fading; and a receiver adopts full-digital receiving, can fully utilizes array and diversity gains of the analog beam formation and multiplexing and diversity gains of digital beam formation under reasonable receiver complexity, thereby improving system performance.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a separate asymmetric hybrid beamforming transmission device and method suitable for high-frequency multiple-input multiple-output systems. The transmission device and method adopt the asymmetrical beamforming scheme of transmitter separation type digital and analog hybrid beamforming to transmit, receiver all digital reception, and can make full use of the array, diversity gain and digital beamforming of analog beamforming under reasonable receiver complexity. The multiplexing and diversity gain of beamforming improves system performance. Background technique [0002] Facing 2020 and the future, mobile communication technology and industry will enter the development stage of the fifth generation mobile communication (5G). China proposed a data rate index of 100Mbps-1Gbps in the IMT-2020 (5G) network technology architecture white paper. In order to ach...
