Abstract
A fast frequency hopped spread spectrum system is described which employs a wideband receiver to detect partial-band jamming. We assume that the interference is locally statistically stationary over numbers of hop intervals. The signal energy of each channel is first calculated and then compared with a threshold to determine whether the channel is jammed. Different threshold configuration method is discussed. It is shown that the interference can be detected in very low jamming to signal plus noise ratio.
