Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0045] Most of the current communication methods use digital communication, such as satellite communication, mobile phone, microwave communication and so on. In digital communication, the transmitted information is represented by 0 / 1 bit. According to the different modulation methods used, each 1 or more bits can be represented by a symbol. Different symbols are represented by different waveforms according to the different bits carried. In this way, the symbol sequ...

Abstract

The embodiment of the present invention discloses a symbol detection method, device and communication equipment, grouping the sampling sequence without symbol synchronization, and determining a symbol in an iterative manner according to each group of sampling points, compared with the traditional symbol detection method , there is no need to calculate the symbol timing parameters, and at the same time avoid the process of interpolating and recovering the best sampling point position according to the timing parameters, thus simplifying the symbol detection process.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a symbol detection method, device and communication equipment. Background technique [0002] Most of the existing communication methods adopt digital communication, such as satellite communication, mobile phone, microwave communication and so on. In digital communication, the transmitted information is represented by 0 / 1 bit. According to the different modulation methods used, each bit or multiple bits of information can be represented by a symbol. Different symbols are represented by different waveforms according to the different bits carried. , so that the symbol sequence corresponds to the waveform of the communication signal, which is transmitted by wireless or wired electromagnetic waves. At the receiving end of the communication signal, each symbol needs to be recovered, so that the corresponding bit information can be obtained to complete the commun...
