Embodiment Construction

[0026] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0027] see figure 1 As shown, an asymmetric shared hybrid beamforming transceiver device includes a transmitting end and a receiving end. The transmitting end adopts a shared digital-analog hybrid beamforming structure, that is, the signal transmitted on each antenna of the transmitting end is digitally pre-processed For signals obtained by mixing coding and analog precoding, the receiving end only uses a digital beamforming structure, and the transceiver implements multi-user MIMO communication.

[0028] The transmitting end includes a baseband precoder, a digital-to-analog converter, an RF precoder, a mixer and a transmitting antenna connected in...

Abstract

The invention belongs to the technical field of wireless communications, and discloses an asymmetrical shared hybrid beam forming transmitting-receiving device. A transmitting end adopts a shared digital-analog hybrid beam forming structure, and a receiving end adopts a digital beam forming structure. Compared with a system adopting a digital beam forming framework in a conventional MIMO (Multiple Input Multiple Output) communication, the device has the advantages that an RF (Radio Frequency) pre-coder constructed by an analog phase shifter is used at the transmitting end, so that the number of radio-frequency links can be reduced; cost is lowered; and total transmitting power is lowered. Compared with a system in which hybrid digital-analog beam forming structures used at the transmitting end and the receiving end, the device has the advantages that only the digital beam forming structure is used at the receiving end of a system model, so that the beam forming structure at the receiving end is simplified, and the overall system complexity is lowered.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to an asymmetric shared hybrid beamforming transceiver device, which can realize multi-user multiple input multiple output (Multiple Input Multiple Output, MIMO) communication, simplifies the beam forming structure of the receiving end, and reduces the system cost. the complexity. Background technique [0002] With the continuous development of communication technology, communication equipment is constantly updated and improved, and the rapid growth of various data services has put forward higher requirements for the transmission rate of next-generation wireless communication systems including mobile data communication and wireless LAN. The research on high-speed wireless communication with gigabit (Gbps) bit rate has become a hot spot in academia and industry. The millimeter wave frequency band has become one of the main candidate frequency bands for a new generation o...
