Abstract
In this paper, based on a new pulse waveform design algorithm of ultra wideband pulse [5], we employ this algorithm into a cognitive M-ary code selected direct sequence bipolar pulse amplitude modulation ultra wideband communication system. This M-ary DS-UWB system can utilize the cognitive waveform to realize the high performance and high data rate cognitive communication. The bit error rate performance of the M-ary system with the novel pulse waveform is presented in this paper. The proposed scheme can be realized under different situations with lower interference to primary wireless devices and acceptable system complexity. Further more, through the pulse design, we can also generate some good candidate waveform sets which satisfy the FCC regulation.
