Problems solved by technology

SFBC performs block coding on the frequency domain data, but if it is coded directly in order, the original frequency domain structure of the signal will be destroyed, resulting in an increase in its PAPR, which no longer has the low PAPR characteristics of SC-FDMA signals

Abstract

The application discloses a coding method and device based on a multi-antenna transmitting module, a terminal and a storage medium. The method comprises the steps: carrying out serial-parallel conversion of a serial data sequence to obtain a plurality of groups of parallel data sequences; performing Fourier transform on the plurality of groups of parallel data sequences by using a plurality of Fourier transform units in a Fourier transform unit group to obtain a plurality of groups of frequency domain data sequences; determining a plurality of to-be-coded frequency domain data groups based onthe plurality of groups of frequency domain data sequences, configuring each to-be-coded frequency domain data group to comprise one frequency domain data in each frequency domain data sequence, and setting subcarriers spaced between any two adjacent to-be-coded frequency domain data in each to-be-coded frequency domain data group to be the same; and coding the plurality of to-be-coded frequency domain data groups according to a preset code word matrix to obtain N groups of coded data corresponding to N transmitting antennas. Therefore, the recombined to-be-coded frequency domain data groups are coded to enable the transmitted data (signals) to have a low peak-to-average ratio.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a coding method, device, terminal and storage medium based on a multi-antenna transmitting module. Background technique [0002] Orthogonal Frequency Division Multiplexing (OFDM) is one of the main technologies of today's broadband wireless communication systems. It distributes the data symbols to be sent to a given number of orthogonal sub-carriers in the frequency domain for modulation and transmission. Each sub-carrier is transmitted in parallel at a lower symbol rate, which is equivalent to converting a wideband frequency selective fading channel For narrowband channels with multiple flat fading. Adding a cyclic prefix (Cyclic Prefix, CP) can effectively combat the multipath effect of the channel and achieve high-speed reliable communication. Multiple-Input Multiple-Output (Multiple-Input Multiple-Output, MIMO) technology is a technology that uses multi...
