Symbol Period based Energy Detector.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
This thesis deals with signal detection which is very essential in wireless communications, RADAR and Cognitive radio. In particular, detection of digitally modulated signals is considered in this thesis. Due to presense of carrier in digital modulated signal, certain symmetries can be identified in the received signal. Assuming the knowledge of signal bandwidth, we propose a novel detector for digital modulated signals using identified symmetry properties. A very good amount of literature survey is given for existing detectors and followed by design and analysis of our proposed detector named Symbol Period based Energy Detector(SPEED). Extensive simulation results are given for BPSK and 16-QAM signals to corrobarate analysis of SPEED and are compared with Conventional energy detector, Improved energy detector and Cyclostationary detector. These results show that SPEED performs much better than other detectors.
