DATA PROCESSING METHOD AND TRANSMITTING DEVICE Russian patent published in 2021 - IPC H04B7/06 

FIELD: communications.

SUBSTANCE: invention relates to the field of communications and, in particular, to space diversity technology, which is based on multiple access and is used in a wireless communication system. The data processing method includes: generating, by the transmitting device based on a bit stream, a single level of a sequence of modulation symbols, which includes N modulation vectors, wherein any modulation vector includes U modulation symbols, U ≥ 2, N ≥ i ≥ 1 and N is a positive integer; and processing, by the transmitting device of modulation vector using matrix to obtain the modulation matrix, wherein each modulation matrix includes T elements in the first dimension, T is the value of the spatial domain resources, T is ≥ 2, and modulation matrix is used to map the bit stream to spatial domain resources T. According to the solutions provided in the invention, spatial diversity can be implemented in the code domain in order to increase the reliability of transmission.

EFFECT: combining multichannel input - multichannel output technology with subcarrier multiple access technology.
