Abstract:

Receivers () and methods of adaptively adjusting the receivers based on a received interferer are described. The peak-to-average ratio of a received signal is used to determine the type of interferer. The ratio and interferer type, in addition to the type of on-channel signal, are used to select parameters to adjust the decay time of a peak detector (), and the threshold and hysteresis of a comparator (). The peak detector () and comparator () are used to generate an off-channel flag that indicates the presence of a relatively strong interferer to other modules in the receiver (). If valid data is not present a default set of parameters is provided. The ratio is determined by dividing the maximum peak over the average or a range of ratios is determined by comparing a scaled value of the average to different scaled values of the peak.
