Problems solved by technology

[0003] In related technologies, signals that have not undergone probability shaping and signals that have undergone probability shaping mapping are interleaved by an interleaver. However, in the process of signal interleaving, the arrangement of signals is prone to crosstalk, resulting in the inability to perform signal shaping. gain

Abstract

The invention provides a data sending method, a data receiving method, a terminal, a system, equipment and a readable storage medium, and the data sending method comprises the steps: obtaining to-be-sent source data; probability shaping processing is conducted on the source data, probability mapping data are obtained, the probability mapping data comprise shaped data and unshaped data, the shaped data are stored in a shaped data array, and the unshaped data are stored in an unshaped data array; performing pre-interleaving processing on the probability mapping data to obtain interleaved data; performing forward error correction coding processing on the interleaved data to obtain verification data, and performing post-interleaving processing on the interleaved data and the coded data to obtain data to be modulated; and performing modulation processing on the data to be modulated, and obtaining modulation symbol data. According to the embodiment of the invention, the signals can be arranged according to the preset mode in the signal interleaving process, so that the signals can be modulated and mapped, and shaping gain is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data sending method, a data receiving method, a terminal, electronic equipment, a data communication system, and a readable storage medium. Background technique [0002] In the communication transmission system, the shaping gain is generated by probabilistic shaping of the input signal, thereby reducing the average power of the signal and increasing the transmission distance of the system. [0003] In related technologies, signals that have not undergone probability shaping and signals that have undergone probability shaping mapping are interleaved by an interleaver. However, in the process of signal interleaving, the arrangement of signals is prone to crosstalk, resulting in the inability to perform signal shaping. gain. Contents of the invention [0004] Embodiments of the present application provide data sending and receiving methods, terminals, systems, devices, and rea...
