Minghao Tian · Journal of Shenyang Ligong University · 2010
Differential frequency hopping(DFH) is a new frequency hopping spread spectrum.A key concept in CHESS design is the use of a differential frequency hopping technique,which mainly is an algorithm of frequecy converter function(function G),which merges information modulation and frequency hopping patterns together.Based on principle of function G,RS code which takes on better modification capability control subset of frequency hopping.In this paper,we present to use a new method to improve frequecy performance.The patterns are analyzed and tested.The results show that frequency hopping patterns generated by the new algorithm have better randomicity and uniformity.
