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.
