Performance Analysis of Families of Frequency-hopping Sequences Based on M-sequences and RS Codes
Yan Liu · Jisuanji fangzhen · 2010
Families of frequency hopping sequences are used to specify which frequency will be used for transmission at any given time,and their properties play important roles in FHMA systems. The difficulty of the design is the designed sequences must have excellent anti-jamming capability and correlation properties. The usual method of past is producing families of FH sequences based on m-sequences. The method has obvious defect. The paper proposes a new method that produces families of FH sequences based on RS codes. The new method increases the complexity of these sequences and raises anti-jamming capability and network capacity. According to the hamming correlation criteria,the paper simulates the properties of those sequences by MATLAB and verifies theirs reliability,feasibility and superiority.
