Description

technical field [0001] The invention belongs to the field of coding cooperative communication, and in particular relates to an energy-carrying transmission protocol applied to a code-carrying energy-carrying relay cooperation system. Background technique [0002] The basic idea of ​​the cooperation technology is that single-antenna terminals cooperate to share each other's antennas to form a virtual Multiple-Input Multiple-Output (MIMO) system, so that single-antenna terminals can obtain the advantages brought by MIMO technology. Cooperative technology is a new way to utilize space resources, and its advantages are mainly reflected in: (1) obtaining space diversity gain; (2) expanding communication coverage; (3) reducing communication blind spots.

Problems solved by technology

There are three main types of SWIPT transmission protocols, namely protocol 1: based on time switching protocol, which switches ID and EH modes in each symbol transmission cycle, which has high processing complexity and requires strict symbol synchronization; protocol 2: based on power division protocol, which divides the received signal power into two power flows, which are used to realize ID and EH functions respectively, which requires extremely high hardware circuits; protocol three: based on the antenna switching protocol, this protocol divides multiple antennas into two types, one One class is used to implement the ID function, and the other class is used to implement the EH function. It is simple to implement based on the antenna switching protocol, but it is not suitable for single-antenna situations.

The existing research on energy-carrying relay cooperation mainly focuses on AF and DF methods. As far as we know, there are few literature reports on energy-carrying relay cooperation in the coded cooperation mode.
