Abstract

The invention discloses a decoding method and device based on overlapping multiplexing, and the method comprises the steps: S1, obtaining a received signal which is a signal obtained through carryingout the coding modulation of an input signal according to a multiplexing waveform matrix; S2, calculating a first zero setting matrix according to the multiplexing waveform matrix, and performing zero-forcing detection estimation on the input signal according to the received signal and the first zero setting matrix to obtain an initial estimation value; And S3, recovering the input signal according to the initial estimation value. A combination zero forcing-parallel interference cancellation detection algorithm is used for correspondingly decoding the received signal, so that the decoding complexity of the OvXDM system is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication systems, in particular to a decoding method and device. Background technique [0002] For the OvXDM system, where X can represent time T, frequency F, code division C, space S or mixed H, etc., commonly used decoding methods include Viterbi decoding algorithm, MAP, Log-MAP and other decoding methods, among which Viterbi The ratio decoding algorithm is based on graph decoding, and the complexity is affected by the number of states. For the OvXDM system, when the number of overlapping multiplexing K is large, its decoding complexity increases exponentially, and requires a large storage capacity, which makes it difficult to implement in actual engineering. [0003] Aiming at the problem of high decoding complexity of the OvXDM system in the related art, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at the problem of high decoding complexity o...
