Real-Time Implementation of Periodogram Based Spectrum Sensing Detector in TV Bands
Original language description
This paper deals with real time implementation of spectrum sensing method used for detection in TV bands. The most common and simplest method of spectrum sensing is based on the energy detection principle (using Periodogram, Bartlett and Welch methods).Intermediate frequency band signal of TV receiver was used in real-time implementation. The main algorithm was implemented on the Memec Development Board with FPGA Virtex IV and with A/D (D/A) converters assembled on analogue module P240. Humax F3-FOX Twas chosen as a television receiver. Our results were compared with Matlab simulations based on the same input signals. It shows that we can detect free spaces in the TV channels. The real time realization can be used as an important part of Cognitive Radio chain.
