Efficient signal decoding system

Abstract

The invention discloses an efficient signal decoding system. The system comprises a signal transmitting end and a signal receiving end, and the signal transmitting end comprises a transmitting end baseband processing module, a transmitting end radio frequency processing module, a transmitting end frequency hopping pattern configuration module, a feedback channel receiving module, a transmitting end frequency hopping pattern storage module, an interrupt signal receiving module, a waiting clock control module and a waiting clock storage module. The three sets of frequency hopping pattern frequency points which are matched with one another are configured at the signal transmitting end and the signal receiving end, once disturbance is found on some frequency points, the frequency points are avoided in frequency hopping and are switched to other frequency points, and the error code phenomenon caused by the disturbance of the frequency points is avoided. The coding and decoding mode in the scheme can hide the coded signal on the premise of destroying the frequency characteristics of the original signal to a minimum extent, and has relatively strong practicability.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an efficient signal decoding system. Background technique [0002] With the development of radio communication technology, the frequency hopping communication system has been widely used, and the security problem has become a focus of people's attention. Frequency hopping communication is a kind of digital communication and a kind of spread spectrum communication. In this communication method, the radio frequency bandwidth used for signal transmission is dozens, hundreds or even thousands of times of the original signal bandwidth. But only for a certain moment, it only works on a certain frequency. Its main function is to change the carrier wave transmitted by frequency hopping communication according to a certain regular random hopping sequence. Frequency hopping communication is an effective means of anti-interference and anti-intercept communication in the...

Problems solved by technology

Since the quality analysis of the frequency point of the frequency set is not carried out during communication, if the frequency point is severely interfered, the information transmitted by the frequency point is difficult to extract, resulting in a large number of bit errors, making it impossible for the receiving end to obtain correct information, making information transmission efficient very low
