频谱感知是实现未来认知无线电中最具挑战性的任务之一。传感单元应以小延迟和低功耗提供有关周围无线电频谱的可靠信息。本文提出了一种能够执行循环平稳特征检测和能量检测频谱估计的频谱感知单元的实现。在 FPGA 上设计原型用于测量和演示，65 nm CMOS 工艺的综合提供了 ASIC 实现中面积和功耗的估计。
Spectrum sensing is one of the most challenging task in implementing future cognitive radios. The sensing unit should provide reliable information about the surrounding radio spectrum with small delay and low power consumption. This paper presents an implementation of a spectrum sensing unit capable of performing both cyclostationary feature detection and spectrum estimation for energy detection. A prototype is designed on a FPGA for measurement and demonstration, and synthesis for 65 nm CMOS process provides estimates for area and power consumption in an ASIC implementation.
