Abstract

The invention discloses a data processing method and device. The method comprises the following steps: carrying out preset pure overlapped multiplexing coding on a bit stream obtained in advance to obtain an output symbol sequence; recursively encoding the output symbol sequence through preset offset overlapped multiplexing encoding to obtain a to-be-sent signal; wherein the recursive encoding isperformed on the output symbol sequence through the preset offset overlapped multiplexing encoding, and the step of obtaining the to-be-sent signal comprises the following sub-steps: carrying out recursive processing on the output symbol sequence to obtain a data sequence; overlapping multiplexing coding is carried out on the data sequence to obtain an output symbol stream; and determining the output symbol stream as a to-be-sent signal. According to the method, the problem that the threshold signal-to-noise ratio is also improved along with the improvement of the spectrum efficiency of an actual system is solved; the technical problems that a large number of levels are needed under high spectral efficiency, the system complexity is high, and the performance advantage is not obvious underlow spectral efficiency are solved.

Description

technical field [0001] The present invention relates to the application field of communication technology, in particular, to a data processing method and device. Background technique [0002] Overlap multiplexing OvXDM (X represents any domain, including: time domain T, space domain S, frequency domain F, code division domain C or hybrid domain H, etc.) system, its main advantage is that it can greatly improve the transmission spectrum efficiency of the system, However, as the spectral efficiency increases, the threshold signal-to-noise ratio will also increase. And in the case of low spectral efficiency, the coding gain is low, and the performance is not obvious compared with other actual systems; and in the M-QAM system with the same spectral efficiency, the number of levels required by the M-QAM system is relatively high, and the system's The complexity is also higher. [0003] Aiming at the above-mentioned problems that the threshold signal-to-noise ratio of the actual...
