To improve the randomness and uniformity of a differential frequency hopping sequence,a new frequency transform function algorithm is proposed based on a study of differential frequency hopping technology and the present frequency transform function algorithms. This algorithm adopts an optimized chaotic sequence to disturb the data information codes for good data randomness. It also employs the RS (Reed-Solomon) codes of good capability in correcting errors and the m sequence to control the frequency hopping interval and the frequency subsets for better characteristics of the frequency hopping sequence. The randomness and uniformity of the differential frequency hopping sequence utilizing the proposed algorithm are validated by simulation. A comparison with the frequency hopping sequences generated by one G function algorithm based on chaotic sequences and another based on RS code and m sequences shows that the favorable randomness and uniformity of the differential frequency hopping sequence generated with the new frequency transform function algorithm is improved.
