Title:
ADJACENT CHANNEL REJECTION OF A CCK BLOCKER
Document Type and Number:
WIPO Patent Application WO/2012/092162
Kind Code:
A3
Abstract:
An adjacent channel interference rejection mechanism is provided to detect and reject CCK-modulated signals from an adjacent channel in a wireless communication receiver. Replicas of the baseband signals are frequency-shifted and then analyzed through a series of correlations to compare the power of the correlation outputs. An adjacent channel interference of a CCK-modulated signal is determined and rejected based on the comparisons meeting a predetermined tolerance level.
