一种异构可重构的认知无线电平台及设计方法

未来无线通信频带越来越紧张,认知无线电可感知频谱,使认知用户和认证用户可以无干扰地共享频谱,并成为一种提高频谱利用率的重要方法。提出了一种基于SoC(System on Chip)的异构可重构认知无线电平台及设计方法,该方法满足认知无线电感知频谱、适应无线信道时变的要求,并能高效、低能耗地实现认知无线电的动态配置。

A heterogeneous reconfigurable cognitive radio platform and its design method

With the growth of future wireless networks, there will be a crisis of spectrum availability under the current spectrum allocation scheme. Cognitive radio is able to sense the spectrum, makes cognitive users share the spectrum with the licensed users on a non-interferencs basis and improves the spectrum utilization. In this paper, we propose a cognitive radio system architecture based on SoC and discuss its design on a heterogeneous reconfigurable radio platform. This platform can be used to realize the adaptation required by the cognitive radio.
