Embodiment Construction

[0078] The data processing method and device provided by the embodiments of the present invention can be applied to MIMO-OFDM-IM and the data transmission process in the system.

[0079] Please refer to figure 1 , which shows a schematic structural diagram of a MIMO-OFDM-IM system provided by an embodiment of the present invention. Such as figure 1 As shown, the MIMO-OFDM-IM system includes: T MIMO-OFDM-IM branches. Each MIMO-OFDM-IM branch in the T MIMO-OFDM-IM branches includes: an OFDM-IM module, a coded modulation module, and an inverse fast Fourier transform (English: Inverse Fast Fourier Transform, referred to as: IFFT) module and cyclic prefix (English: CyclicPrefix, referred to as: CP) module.

[0080] Specifically, in a branch of the MIMO-OFDM-IM system, the sending end divides the m*T information bits to be sent into T groups, and each group in the T groups has m-bit information; the sending end divides the m*T information bits of each group Bit information is di...

Abstract

The embodiment of the invention discloses a data processing method and a data processing device, and relates to the technical field of communication. According to the invention, the problems that during the signal fading process of data sent by the antenna of a sending end, a receiving end cannot correctly demodulate the data sent by the antenna and the reliability of data transmission is low canbe solved. According to the technical scheme of the invention, the sending end divides the to-be-sent information into a first group of bits and a second group of bits. The sending end performs firsttreatment on the first group of bits to obtain at least two modulation symbols, wherein the first treatment at least comprises the modulation step. The second group of bits is used for the sending endto select at least one group of coding structures from at least two groups of coding structures. The sending end obtains at least one group of coding information based on at least two modulation symbols, at least one group of coding structures and a first parameter set. The first parameter set comprises at least one of a modulation order and an optimization coefficient set. The sending end sendsout the at least one group of coding information. The embodiment of the invention is applied to the data sending process.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a data processing method and device. Background technique [0002] Orthogonal Frequency Division Multiplexing-Index Modulation (English: Orthogonal Frequency Division Multiplexing-Index Modulation, referred to as OFDM-IM) system is a single-antenna system. In the OFDM-IM system, some subcarriers can be selected as active subcarriers for transmission. data. Among them, the OFDM-IM system can modulate the data to be transmitted to the antenna through the phase-shift keying (English: Phase-Shift Keying, referred to as: PSK) / quadrature amplitude modulation (English: Quadrature Amplitude Modulation, referred to as: QAM) modulation method transmitted on the active subcarriers. [0003] In order to increase the data transmission rate, the OFDM-IM system can be combined with a multiple-input multiple-output (English: Multiple-Input Multiple-Output-...
