Abstract

The invention discloses an overlapping multiplexing system, a processing method and device thereof, a storage medium and a processor. The method comprises the following steps: receiving a multi-channel coding sequence output by a sending end, the multi-channel coding sequence being a sequence obtained by performing error correction code coding, overlapped multiplexing coding and space-time codingon an input sequence; detecting the multi-channel coding sequence by using a serial interference cancellation detection algorithm to obtain a detection result; judging the detection result to obtain ajudgment output sequence; and performing error correction code decoding on the judgment output sequence to obtain a decoded sequence. The data transmission rate of the overlapped multiplexing systemin the prior art is improved, and the technical problem that the overlapped multiplexing system in the prior art is a single-antenna system and is low in data transmission rate is solved.

Description

technical field [0001] The present invention relates to the field of overlapping multiplexing systems, in particular to an overlapping multiplexing system and its processing method and device, storage medium, and processor. Background technique [0002] The current overlapping multiplexing system OvXDM (X represents any domain, including: time domain T, space domain S, frequency domain F, code division domain C or hybrid domain H, etc.) is mainly used in single-antenna systems without utilizing spatial information. Moreover, the existing multi-antenna technology is not suitable for the overlapping multiplexing system, and when a large amount of data is transmitted, its transmission rate is lower than that of the multi-antenna overlapping multiplexing system. [0003] There is no effective solution to the problem that the overlapping multiplexing system in the prior art is a single-antenna system and the data transmission rate is low. Contents of the invention [0004] An ...
