Description

Technical field [0001] The present invention relates to the field of communications, in particular to a data transmission method, device, storage medium and processor. Background technique [0002] In the communication system, using overlapping multiplexing coding to encode data can greatly improve the transmission spectrum efficiency of the system. However, the overlapping multiplexing coding coding method has lower error correction ability for information flow and higher transmission reliability. Poor; and 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 using spatial information , When the transmission data is large, compared with the multi-antenna overlapping system, the transmission rate is lower. [0003] There is no effective solution to the problem of poor transmission reliability and low...
