本文提出了一种基于压缩啁啾波形和改进变换域通信系统（TDCS）的认知无线电超宽带（CR-UWB）脉冲。该脉冲可以感知无线电环境，并使用超宽带作为通用物理层来适应各种无线信道条件，并利用任何超宽带掩模的无干扰频谱，从而避免对现有无线系统的干扰。这种脉冲可以通过表面声波（SAW）器件和其他一些辅助器件来实现。在UWB系统中，使用该脉冲可以明显改善系统的误码率性能。
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.
