Abstract

The invention discloses an overlapping multiplexing system and a processing method and device thereof. The method comprises the following steps: converting at least three paths of parallel data streams in the overlapped multiplexing system into serial data streams; wherein the serial data stream is used for obtaining target information, and obtaining the target information by converting the serialdata stream into a parallel data stream through the receiving end and decoding the parallel data stream through at least three decoders. According to the invention, the effect of improving the reliability of information transmission in the overlapped multiplexing system is achieved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to an overlapping multiplexing system and a processing method and device thereof. Background technique [0002] At present, the traditional overlapping multiplexing system (Turbo-OvXDM) is a two-dimensional cascade system. After the two identical data streams pass through the interleaver, two data streams with low correlation are formed. Perform OvXDM encoding separately, and then combine the encoded data streams for transmission. [0003] figure 1 It is a schematic diagram of a transmitting end of a two-dimensional Turbo-OvTDM system in the related art. Such as figure 1 As shown, the OvXDM system of the Turbo structure adopts a structure similar to the Turbo code. The Turbo code concatenates two simple component codes in parallel through a pseudo-random interleaver to construct a long code with pseudo-random characteristics, and through two soft input Pseudo-random decoding is ac...
