Abstract

The invention discloses a wireless relay communication system, which includes a signal source node, a destination node and N relay nodes. The wireless relay communication system determines the nth relay node as the relay node for transmitting signals according to the system receiving signal-to-interference ratio and preset relay node selection criteria. The signal source node sends the transmission signal to the nth relay node in the first time slot, and the node retransmits the transmission signal to the destination node in the second time slot. When the above N relay nodes have a storage function, the relay system only includes a number of mutually independent second-hop links, and according to the corresponding preset relay node selection criteria, determine the nth relay node as the transmission signal The relay node sends the transmission signal to the destination node. The technical scheme of the present invention proposes several relay selection criteria to select the best relay to suppress interference to assist data transmission, effectively suppress the influence of interference signals on the double-hop relay communication system, and improve the anti-interference performance of the communication system.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a wireless relay communication system. Background technique [0002] With the continuous improvement of communication coverage and quality requirements, cooperative relay technology is considered to be a technology that can provide greater network coverage and capacity, improve communication system performance, and improve system robustness. Cooperative relay communication technology has been widely used in practical applications, and it is divided into two categories, including: transparent relay protocol and regenerative relay protocol. The transparent relay protocol does not perform digital processing on the information, for example, only perform operations such as amplification and forwarding (AF) or phase rotation. The regenerative relay protocol performs a series of digital processing on the information and then forwards it, such as Decoding and Forwa...
