Abstract :
UWB systems hold significant potential to serve as covert communications systems with a low probability of detection (LPD). In this paper, the performance and covertness of binary and M-ary pulse position modulation, bipolar as well as bipolar PPM modulation schemes are evaluated for UWB. The effect of channel coding on the covertness of UWB is also considered. Two radiometer-based detection systems are compared for use in the detection of impulse radio.
