Abstract:
1. A communication unit for use in a wireless communication system operating in a first frequency band, said communication unit comprising: a receiver unit for processing a received signal in the first frequency band; a signal detector configured to receive the processed signal from the receiver unit and detect a wanted signal; interference detection circuitry configured to detect the presence of an interfering pulse and feed information about the presence of the interfering pulse to the signal detector; a directional coupler configured to direct a fraction of the received signal to the interference detection circuitry; and a signal to noise ratio (SNR) calculator configured to receive the wanted signal from the signal detector, and to calculate an SNR of the wanted signal, predict a relationship between the SNR of the wanted signal and the interfering pulse, and forward information about said relationship to the signal detector; wherein the signal detector is arranged to modify a detection algorithm based on the information about the relationship between the SNR of the wanted signal and the interfering pulse.
