Due to its ability to provide high data rates and its effectiveness against multi-path delay spread commonly encountered in mobile communications channel, Orthogonal Frequency Division Multiplexing (OFDM) has been the modulation of choice for many current wireless communication standards including IEEE 802.11(WLAN), IEEE 802.16(WiMAX), IEEE 802.22(WRAN) and DVB-T. The IEEE 802.22 standard is now known...
Spectrum sensing is an integral part of Cognitive radio, a radio that seeks to address perceived spectrum scarcity that studies have shown was rather caused by inefficient utilization of the available spectrum. In this paper, a spectrum sensing system using energy detection for analog TV and FM broadcast transmitters, and modified ISDB-T signal was implemented in a Software-defined radio platform...
