Cognitive Impulse Ultra Wide Band Spectrum Sharing Radio and Pulse Shaping
Feng Shan Zhang, Cai Feng Liang · Applied Mechanics and Materials · 2013
Both underlay spectrum sharing radios and overlay spectrum sharing radios have their advantages and disadvantages. Ultra wide band (UWB) and cognitive radio (CR) are important underlay and overlay technology respectively used as secondary radio systems. In this paper, a cognitive impulse ultra wide band (CIUWB) spectrum sharing radio technology is presented based on impulse UWB and CR.
