Software Defined Radio Signal Detector Implementation using FPGA

Rohan Fernandes, Shubhangi Mahamuni

Abstract: Signal detection is the very critical task upon which the entire operation of the radio device rests. Software-Defined Radio (SDR) is a technology that most of traditional radio applications are implemented in software. It has the advantages like re-configurability and flexibility, SDR system has to face a critical challenge of realtime processing due to high sampling rates and latency. Signal detection methods in radio signal detection has gained new aspects with awareness of cognitive radio systems. The requirement of spectrum sensing has been eliminated recently by FCC. The objective is to increase the bandwidth, keep low latency and reduce the power consumption without reducing the flexibility of a software radio. The implementation of signal detector on FPGA would reduce the power consumption due to signal processing done on a software defined radio by a host computer and increase data rate of a software radio. This is justified by developing application of aircraft tracking and FM.
