Energy Detection Based Spectrum Sensing Technique for Software Defined Radio

Tapan K Das | Yashaswini Sharma

Abstract: A lot of hardware components are used to make a conventional radio communication system, the complexity of these hardware can be reduced with help of Software Defined Radio (SDR) which is a form of wireless communication. Software Defined Radio implemented system allows us to make alteration in it or operate it with help of a software, thus making the system flexible and reconfigurable. The system changes from single mode or single band to multi-mode, multi-band as we can change the functionality and parameters of the system with the help of a software. The hardware components of a traditional radio communication system such as converters, modulator, demodulator, detector, filter, etc, make the platform cost very high and increases the complexity of a system. Software Defined Radio helps in excluding all the hardware from the system as it replaces them by pure software. In SDR modulation plays a very vital role as different modulation techniques are very important part of wireless technology and radio communication. This paper discusses about the amplitude modulation in brief and also discusses the optimized utilization of spectrum resources with help of software defined radio.
