Implementation of spectrum sensing on wireless open-access research platform

Abstract

Opportunistic spectrum usage is one application of the so called cognitive communication systems that enables efficient spectrum usage in future wireless communication systems. One of the key features in opportunistic spectrum usage is a spectrum opportunity estimation method. Energy detection has the benefit that knowledge about the licensed users is not required. In this paper, energy detection method called the localization algorithm based on double-thresholding (LAD) is implemented on the wireless open-access research platform (WARP). The simulation measurements proved that the implementation was done correctly. Results included important information of consumed FPGA resources and processing latencies for the LAD method implementation.
