Abstract :
We propose a novel pulse for cognitive radio-ultra wideband (CR-UWB) using the compressed chirp waveforms and modified transform domain communication system (TDCS) in this paper. This pulse can sense the radio environment, and uses UWB as a versatile PHY layer to adapt various wireless channel conditions, and utilizes the interference free spectrum of any UWB masks, thereby, it can avoid interference to/from the existing wireless systems. This pulse can be implemented using surface acoustic wave (SAW) devices and some other accessorial devices. The bit error ratio (BER) performance of system using this pulse can be observably improved for UWB systems.
