Abstract

This day the spectrum is a very limited and a scare resource, as the applications are developed so fast and depends on the frequency spectrum whether it a mobile telephony or movie on demand or anything. In this paper we present, our in-progress research result which we get during our research work. In this work we use the open source software GNU Radio and ultra-Chief SDR device: RTL 2832 U. We sensed the Real time signal from the environment Belongs to GSM Downlink Frequency.

Abstract

In wireless communication frequency spectrum is a scare element. This is also costly and limited. So, its effective use is necessary. The cognitive radio is the technology which makes it possible to senses and uses the white space available into the spectrum used by the primary user without any kind of interference. In cognitive radio spectrum sensing is the most interesting and challenging task .In this paper we discussed about the spectrum sensing Techniques and challenges face in sensing the spectrum.
