认知无线电需要一个智能MAC层与灵活的PHY层耦合。大多数实现方式使用软件定义的无线电平台,其中MAC和PHY都以软件实现,但这可能导致长的处理延迟,并且使得高级基带处理无法实现。虽然基于FPGA的SDR平台确实存在,但它们很难使用,需要大量的工程专业知识,并且添加动态行为更加困难。现代混合FPGA将FPGA结构与功能强大的嵌入式处理器紧密耦合,允许基带在硬件中实现,MAC在软件中实现。我们展示了一个平台,使无线电设计人员能够使用Xilinx Zynq构建动态认知无线电,并进行部分重新配置,从而通过抽象软件控制实现真正动态、低功耗、高性能的认知无线电。
Cognitive radios require an intelligent MAC layer coupled with a flexible PHY layer. Most implementations use software defined radio platforms where the MAC and PHY are both implemented in software, but this can result in long processing latency, and makes advanced baseband processing unattainable. While FPGA based SDR platforms do exist, they are difficult to use, requiring significant engineering expertise, and adding dynamic behaviour is even more difficult. Modern hybrid FPGAs tightly couple an FPGA fabric with a capable embedded processor, allowing the baseband to be implemented in hardware, and the MAC in software. We demonstrate a platform that enables radio designers to build dynamic cognitive radios using the Xilinx Zynq with partial reconfiguration, enabling truly dynamic, low-power, high-performance cognitive radios with abstracted software control.
