Abstract
In this article we propose a novel Dynamic Spectrum Access (DSA) paradigm to combine the benefits of UWB transmission and cognitive radio technology to optimize the efficiency of wireless spectrum usage and maximize the channel capacity. Specifically, this work presents a multi-carrier platform not only transmits over unused spectrum "holes", but transmits over underused spectrum blocks as well, while minimizing interference to existing primary narrowband transmissions. It is also shown that current cognitive radio and UWB transmission are two special cases of the proposed general paradigm. As a direct result, this paradigm offers a high degree of flexibility of spectrum use for next generation wireless communication systems.
