Efficient channel search with sequential probability ratio testing

摘要

Methods and systems for cognitive radio channel searching are shown that include determining an upper threshold and a lower threshold that will find a free channel in a minimum average searching time based on a channel occupancy probability pi0 and the number of channels K, constrained by a target acceptable misdetection probability and a target acceptable false alarm probability. The K channels are searched with a signaling device using the determined upper threshold and lower threshold to find a free channel.
