Abstract

With the real-valued sequences, a new kind of Code Hopping Code Division Multiple Access (CH-CDMA) communication systems is proposed for anti-interception. While the sequence parameters are the same, the number of the real-valued sequence sets are much more than those of the traditional integer sequence, therefore, the codes for hopping are no longer in serious deficiency as they used to be, which makes the performance of anti-interception improved greatly. Moreover, using real-valued sequences with Quasi-Zero Correlation Zone (QZCZ) may eliminate the Inter-Symbol Interference (ISI) and Multi-Access Interference (MAI) so as to overcome the far-near effect and improve the performance of anti-interference.
