Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] A method for generating a cyclic and iterative m-sequence frequency hopping pattern, the method expands the cycle of generating the frequency hopping pattern by multiplying two m-sequence cascades, increases the anti-tracking capability of the frequency hopping communication system, and improves security and confidentiality performance, specifically comprising the following steps :

[0018] (1) According to the instruction sent by the synchronization control unit of the frequency hopping communication system, judge whether the transmitting end and the receiving end of the frequency hopping communication system need to be synchronized, if necessary, reset the transmitting end and the receiving end, and reset the first One m sequence is used as the current first m sequence, and the second m sequence after reset is used as the current second m sequence, and step (2...

Abstract

The invention discloses a method for generating cyclical iteration m sequence frequency hopping patterns in a frequency hopping system. On the basis of present generation methods of m sequence frequency hopping patterns, cyclical iteration is added so that the provided method has more flexible and changeable cycle period and the security of the frequency hopping system is effectively increased compared with previous frequency hopping pattern generation method.

Description

technical field [0001] The invention relates to a method for generating a frequency hopping pattern in a frequency hopping communication system, and is particularly suitable for improving the flexibility of the period length of the frequency hopping pattern and increasing the security and confidentiality of the frequency hopping communication system. Background technique [0002] At present, m-sequences are often used in frequency-hopping communication systems to generate frequency-hopping patterns. Depending on the selected m-sequences, frequency-hopping patterns with different cycle lengths are generated. The samples of frequency-hopping patterns generated in this way are relatively low, and the cycle lengths are not flexible enough. Contents of the invention [0003] The object of the present invention is to avoid the disadvantages of the above-mentioned background technology and provide an m-sequence frequency hopping pattern generation method with more flexible frequen...
