Abstract

The invention relates to a signal processing method and device of a relay system, the relay system, computer equipment and a computer storage medium. The signal processing method of the relay system comprises the steps that when a carrier signal sent by a source node is received, an antenna with the channel gain smaller than a gain threshold value is selected as a signal transmission antenna, andan antenna with the channel gain larger than or equal to the gain threshold value is selected as an energy obtaining antenna; the carrier signal is transmitted to a decoding circuit for signal decoding through the signal transmission antenna; and the energy acquisition antenna is connected with the energy acquisition circuit to acquire energy. On the basis of keeping the maximum system capacity ofthe relay system, the workload of antenna receiving combined search and the like can be reduced, and the signal transmission effect of the relay system is ensured.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a signal processing method and device for a relay system, a relay system, computer equipment, and a computer storage medium. Background technique [0002] Simultaneous wireless information and power transfer (SWIPT) is a relatively advanced technology used to solve the problem of energy shortage in energy-constrained networks. Time selection (Time-switching, TS) protocol and power splitting (Power-splitting, PS) protocol are the most feasible technologies in the simultaneous transmission of wireless energy and information. The cooperative relay system based on the above-mentioned TS protocol or PS protocol is commonly used in wireless signal transmission solutions. [0003] Some scholars proposed a low-complexity antenna selection (Antenna Switching, AS) protocol in the cooperative relay system. In the AS protocol, a part of the antennas of the energy-con...
