On the performance of various spectrum sensing detectors on wireless communication signals

This paper deals with the performance evaluation of various spectrum sensing detectors — from the basic energy detection through the eigenvalue based to goodness-of-fit detector based on the Kolmogorov-Smirnov test. After a brief description of the principles, their performance is evaluated on the real sampled measured signal of the most important communication systems (e.g. GSM-EDGE, WiMAX), broadcasting system DVB-T and custom MQAM modulated signals. The results of the performance are presented in the form of Receiver Operational Characteristic curves.
