Abstract

The invention discloses a small-scale frequency hopping communication system, which includes a baseband signal generation module, a shaping module connected to the baseband signal generation module through a data line, and a bit synchronization clock extraction module. The baseband signal generation module includes sequentially connected controller modules. , a pseudo-random sequence generation module and a filter module, the bit synchronous clock extraction module includes a digital filter module, an edge extraction module, a frequency division coefficient module, a frequency division module, the shaping module is connected with the digital filter module, and the digital filter module One output signal is input to the edge extraction module, another output signal of the digital filter module is input to the frequency division coefficient module, the output terminal of the edge extraction module is connected to a terminal of the frequency division module, and the output terminal of the frequency division coefficient module is obtained It is connected with the other terminal of the frequency division module, and the output terminal of the frequency division module outputs the restored external input signal. The invention has the advantages of simple structure, convenient use, small size and low cost.

Description

technical field [0001] The invention relates to the technical field of communication anti-jamming, in particular to a small frequency hopping communication system. Background technique [0002] Frequency hopping technology is a relatively mature technology at home and abroad. It can effectively avoid interference and exert communication performance. [0003] The traditional small-scale frequency hopping communication system consists of many devices, some of which are complex in structure, large in size, high in cost, and their performance needs to be improved. Therefore, we propose a small-scale frequency-hopping communication system with simpler structure, lower cost and better performance to solve the above existing problems. Contents of the invention [0004] (1) Technical problems to be solved [0005] A small-scale frequency hopping communication system is proposed to solve the problems in the above-mentioned background technology that there are many components, so...
