ZERO DELAY FREQUENCY SWITCHING WITH DYNAMIC FREQUENCY HOPPING FOR COGNITIVE RADIO BASED DYNAMIC SPECTRUM ACCESS NETWORK SYSTEMS

摘要

This invention relates to cognitive radio based wireless communications of dynamic spectrum access networks, and in particular to a method of addressing zero-delay frequency switching for cognitive dynamic frequency hopping. The method combines regular (periodic) channel maintenance with dynamic frequency hopping over a cluster of vacated channels that are initially setup such that the switching delays for channel setup and channel availability check are eliminated.
