Patent Searching and Data


Title:
EFFICIENT CHANNEL SEARCH WITH SEQUENTIAL PROBABILITY RATIO TESTING
Document Type and Number:
WIPO Patent Application WO/2011/112562
Kind Code:
A3
Abstract:
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 πO 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.
