Spread Spectrum Communication Technology of Multi-sub-bandwidth/sub-channel Correlative Frequency Hopping

The development of technology and the communication demand leads to the lack of frequency bandwidth in wireless communication,which is a bottleneck of wireless communication technology.The effect of bandwidth division on the improvement of the frequency spectrum utilization is analyzed under the condition of the multi-access interference and Gaussian white noise.The basic reason why the frequency spectrum utilizatio is not high in the modes of the traditional frequency-division multiplexing(FDM) and spread spectrum communication(SSC) is pointed.A multi-sub-bandwidth/sub-channel correlative frequency hopping communication technology which can improve the frequency spectrum utilization and communication confidentialty is proposed.
