Abstract
Disclosed are a method and system for detecting adjacent channel interference between two systems having neighboring frequencies. The method and system calculates a Fast Fourier Transform (FFT) output for one or more upper and lower frequency side null subcarriers and center data subcarriers of a frequency channel. Power values are calculated for the upper and lower frequency side null subcarriers and the center data subcarriers for use in determining a presence of adjacent channel interference (ACI).
