Real-Time Implementation of Enhanced Energy-Based Detection Technique

The paper explains the development of an efficient energy detection technique and its real-time implementation using wireless access research platform (WARP). An improved energy detection technique is developed named multiple threshold energy detector (MTED). The performance of conventional energy detector is enhanced by using multiple threshold values to compare with the measured values in local sensing. Energy detection has the advantage of detecting the unknown signals. Despite of this advantage, the challenges faced during the hardware implementation of the proposed technique are also addressed. Cooperation-based sensing is implemented to increase the accuracy of detection. Cooperation is achieved using majority rule-based decision fusion scheme. The performance analysis of the implemented energy detection technique is done with respect to the detection probabilities.
