Analysis and generation of few hit zone sequence based on collocation interference mitigation

To solve the problem confronted in FH-CDMA networking communication,the relationship between the method of FH networking and Hamming correlation is illustrated,and a method is proposed to mitigate collocation interference utilizing few-hit zone(FHZ) sequence.Then the generation measure of FHZ sequence is analyzed.Results show that the sequence generated by the proposed method has high performance in condition of quasi-synchronous.Compared with NHZ sequence,it provides a larger system capacity for more user,and collocation interference of FH-CDMA internetworking is reduced remarkably.
