Abstract

The invention is applicable to the technical field of wireless communication, and provides a multi-relay wireless data transmission control method, a communication system and a terminal equipment. Themulti-relay wireless data transmission control method comprises the following steps of constructing a two-hop multi-relay energy-carrying cooperative communication system containing a direct connection link; constructing a data transmission mathematical model of the two-hop multi-relay energy-carrying cooperative communication system by using a power distribution protocol or a time switching protocol; calculating to obtain the optimal throughput of the two-hop multi-relay energy-carrying cooperative communication system by using a convex optimization algorithm according to a data transmissionmathematical model constructed by a power distribution protocol; calculating to obtain the optimal throughput of the two-hop multi-relay energy-carrying cooperative communication system by using a polygon approximation method according to a data transmission mathematical model constructed by a time switching protocol. According to the invention, the existence of direct connection links and multiple relays in a communication system is considered, the method better conforms to a real scene, meanwhile, corresponding solving modes are adopted according to different mathematic models to solve theoptimization problem, and the optimal strategy of the optimization quantity is obtained.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a multi-relay wireless data transmission control method based on radio frequency signal power supply, a multi-relay energy-carrying cooperative communication system and terminal equipment. Background technique [0002] As the number of various electronic devices will increase greatly, a large number of wireless communication devices are powered by batteries with limited capacity. The maintenance cost and life cycle of the equipment largely depend on the battery, which will directly affect the service life of the equipment. . The existing processing method is usually to directly discard the battery after it is depleted or to use a wired connection to supply energy. Although the cost of replacing a battery for a single device is not high, when the number of devices increases massively, direct disposal will cause a lot of waste. And, because of the sheer ...
