Embodiment 1

[0051] figure 1 It is a flow chart of a data sending method provided by Embodiment 1 of the present invention. This embodiment is applicable to the scene where two or more antennas send data. The method can be executed by a data sending device, which can be implemented by software and and / or in the form of hardware, and generally can be integrated in electronic devices. Correspondingly, such as figure 1 As shown, the method includes the following operations:

[0052] S110. Obtain original data to be sent.

[0053] Wherein, the original data to be sent may be data obtained by modulating the original data. For example, modulation methods may include but not limited to phase shift keying modulation, amplitude shift keying modulation, and quadrature amplitude modulation.

[0054]In the embodiment of the present invention, the original bit data can be channel-coded to obtain coded data, and the coded data can be further modulated to obtain the original data to be sent.

Abstract

The embodiment of the invention discloses a data sending method, a data receiving method, an electronic device and a storage medium. The data sending method comprises the steps of obtaining original to-be-sent data; grouping the original to-be-sent data according to a preset data group length to obtain grouped to-be-sent data; performing branching processing on the grouped to-be-sent data according to a non-odd-even branching mode to obtain branching to-be-sent data with a set branching number; generating a set number of sequence antenna data according to each branch to-be-sent data; and generating antenna sending data corresponding to each sending antenna according to each sequence antenna data. According to the technical scheme of the embodiment of the invention, the diversity gain of the antenna can be maximized, the reliability of antenna data transmission is improved, and the application scene of the antenna is expanded.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communication applications, and in particular, to a method for sending and receiving data, an electronic device, and a storage medium. Background technique [0002] Currently, more and more communication devices require more antennas for reliable communication. The data transmission method of the antenna has become an important technical point in the field of communication technology. [0003] In the prior art, for the SC-FDE waveform, in a multi-antenna transmission scenario, generally only the case of two antennas is considered, and the transmission mode of more than two antennas is rarely considered. However, the application scenarios of the two-antenna transmission mode are limited, and the communication signal is poor. Contents of the invention [0004] Embodiments of the present invention provide a method for sending and receiving data, electronic equipment, and a storage m...
