2 Frequency hopping spread spectrum Apparatus and Method based on double random key sharing for low probability of intercept

摘要

The present invention relates to a frequency hopping spread technology. More specifically, the present invention relates to an apparatus and a method of frequency hopping spread to improve signal decoding complexity and to improve the performance of a low probability of intercept by time through signal wiretapping. According to the present invention, the decoding complexity can be exponentially improved by each data symbol through a random key combination (symbol sequence) of a secondary sub channel.
