Method and device for generating frequency-hopping pattern

Abstract

The embodiment of the application provides a method for generating a frequency-hopping pattern, and aims to provide different levels of QoS for users of different priorities when the communication isimplemented with an existing frequency-hopping communication system. The method comprises the following steps: implementing cyclic shift transform on a first randomly-selected frequency-hopping sequence to obtain a first frequency hopping sequence set; deleting the first frequency-hopping sequence in a pseudo-random frequency-hopping sequence set to obtain a second pseudo-random frequency-hoppingsequence set; building a frequency-hopping frequency point calculation function according to a preset frequency hopping sequence constraint condition; calculating each frequency-hopping point in the first frequency-hopping sequence set according to the frequency-hopping point calculation function; building a first frequency-hopping sequence subset according to a calculation result; and mapping each frequency-hopping point in the second pseudo-random frequency-hopping sequence set according to the prebuilt mapping function, and building a second frequency-hopping sequence subset. The application also discloses a device for generating the frequency-hopping pattern.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for generating a frequency hopping pattern. Background technique [0002] Frequency hopping communication means that two or more communication parties are under the control of the same synchronization algorithm and pseudo-random frequency hopping pattern algorithm. Patterns of discrete frequencies hop pseudo-randomly and synchronously. [0003] In frequency hopping communication, the frequency hopping pattern reflects the law of the signal carrier frequency of both parties in the communication, ensuring that the sending frequency of the communicating party is regular and followable. It can be seen that the frequency hopping pattern is the core component of the frequency hopping communication system. Usually the frequency hopping pattern is composed of two parts, one is the frequency hopping frequency point table, in which all available ...
