Abstract

The invention discloses a communication symbol detection method and device, and a computer readable storage medium, and the method comprises the steps: filtering a communication symbol according to afunction expression of a transmission channel corresponding to the communication symbol on a preset basis expansion model when the communication symbol is detected, and obtaining a filtering signal; determining probability distribution of the filtering signal on preset signal classification, and determining a log-likelihood ratio of the communication symbol according to the probability distribution; and determining the type of the communication symbol according to the log-likelihood ratio, and completing the detection of the communication symbol. According to the invention, the symbol detection accuracy is improved from the aspects of channel representation, filtering processing and the like, and the detection performance is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and computer-readable storage medium for detecting communication symbols. Background technique [0002] With the development of communication technology, there are more and more scenarios for high dynamic channels. High dynamic channel means that in some special communication scenarios, due to the complexity and dynamic changes of the environment, it will have a strong dynamic impact on the communication signal, thus affecting the performance of the communication link. From the time domain point of view, it can show strong time-varying characteristics. For example, the communication problem in the plasma sheath environment is characterized by the high dynamic characteristics of the channel in a complex environment. The plasma sheath refers to the plasma wrapped on the surface of the aircraft formed when the spacecraft returns to the earth from ou...
