Problems solved by technology

[0015] When the system adopts high-order modulation methods, such as 16QAM (Quadrature Amplitude Modulation, quadrature amplitude modulation) and 64QAM, the RTS detection algorithm is easy to fall into the circular search of the local domain, resulting in the BER performance of the RTS algorithm and the ML (Maximum Likelihood, maximum likelihood) detection performance, there is a big gap

Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Such as figure 1 As shown, the embodiment of the present invention provides a RI-RTS detection method, including:

[0032] Step 11: The received signal is used as an initial input to perform RTS detection, and it is judged whether the output result after each round of RTS detection satisfies the termination condition.

[0033] Step 121. When the output result does not satisfy the termination condition, random interference is performed on th...

Abstract

An embodiment of the invention discloses an RI-RTS (random interference-reactive tabu search) detection method and device. The RI-RTS detection method comprises steps as follows: a received signal is taken as initial input for RTS detection, and whether an output result after each round of RTS detection meets the end condition is judged; when the output result doesn't meet the end condition, random interference is performed on an output result, a random interference result is obtained and is taken as input for a follow-up round of RTS detection, and RTS detection is executed; when the output result meets the end condition, the RTS detection is stopped, and requirements for system performance and computation complexity are met simultaneously.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a RI-RTS (Random Interference-Reactive Tabu Search, random interference dynamic tabu search) detection method and device. Background technique [0002] In order to further improve the capacity and spectrum efficiency of the mobile communication system, massive MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) technology has been developed rapidly. Generally speaking, in a massive MIMO system, a base station will be equipped with as many as dozens or hundreds of antennas, which is more than 1 to 2 orders of magnitude of the number of antennas in the current communication system. However, with the sharp increase in the number of antennas, the detection complexity at the receiving end will also rise sharply, which will seriously restrict the use of massive MIMO technology in practical communication systems. At present, since the RTS algori...
