Fading Environmental in Generalised Energy Detector of Wireless Incant

Cognitive radio is a radio that can change its transmitter parameters based on interaction with the environment in which it operates. Energy detection is a popular technique for spectrum sensing. But detection performance of energy detector (ED) deteriorates in low signal-to-noise ratio (SNR) conditions and under noise uncertainty. Spectrum sensing of Energy detection for very low signals at the noise floor level and without need to know the signal characteristics in advance. Implementing on Blade RFx40 SDR platform and the performance is going to be analyzed. BladeRFx40 is a Software Defined Radio (SDR) platform and experiment with the multidisciplinary facets of RF communication. It supports; 2x2 MIMO configurable with SMB cable; expandable up to 4x4; RF frequency range 300MHz - 3.8GHz; Stable Linux; Windows; Mac and GNU Radio software support; On-board 200MHz ARM9 with 512KB embedded SRAM (JTAG port available); On-board 15KLE or 115KLE Altera Cyclone 4 E FPGA (JTAG port available).
