Spectrum sensing for WLAN and WIMAX using energy detection technique

Recent trends in wireless communication suffers due to spectrum scarcity. Cognitive radio technology has emerged as potential solution to spectrum scarcity which tries to reuse free underutilized spectrum. Spectrum sensing is the key function for determining underutilized spectrum. This paper discusses receiver operating characteristics (ROC) for energy detection(ED) based spectrum sensing technique in case of BPSK and OFDM modulated signals in WLAN and WIMAX system. And paper provides the performance of energy detection for WLAN and WIMAX application.
