Hybrid duplex relay implementation method based on statistical probability selection

Abstract

The invention provides a hybrid duplex relay implementation method based on statistical probability selection. The method is characterized by comprising the following steps of step 1, pre-judging according to system characteristics, and acquiring system parameters; and step 2, selecting a corresponding working mode according to the system parameters, wherein the system is a one-way decoding and forwarding full-duplex relay system. The hybrid duplex relay implementation method based on the statistical probability selection, which is provided by the invention, focuses on maximization of the throughput of the system, and an optimal relay mechanism based on the statistical probability for a one-way full-duplex / half-duplex hybrid relay system is provided. The hybrid duplex relay implementationmethod based on the statistical probability selection adopts a hybrid duplex mechanism, so that the influence caused by residual self-interference in the full-duplex relay system is eliminated, and the transmission rate of the system is maximized. The relay selects the working mode of the system in each working time slot according to a certain probability.

Description

technical field [0001] The present invention relates to a method, in particular to a hybrid duplex relay implementation method based on statistical probability selection. Background technique [0002] Co-time Co-frequency Full Duplex (CCFD) technology means that the transmitter and receiver of the device occupy the same frequency resources and work at the same time, so that both parties in communication can use the same frequency at the same time in the uplink and downlink. The frequency breaks through the existing frequency division duplex (FDD) and time division duplex (TDD) modes, and is one of the keys for communication nodes to realize two-way communication. At present, the communication systems we know all work in the half-duplex (Half Duplex) state, that is, the uplink and downlink work in different frequency bands or different time periods, for example, Time Division Duplex (Time Division Duplex, TDD) And frequency division duplex system (Frequency Division Duplex, ...
