Spectrum sensing using energy detection for reconfigurable antenna

Rigorous development in Software Defined Radio (SDR) helps to realize the dream of Cognitive Radio. The SDR can be used with a reconfigurable antenna to achieve full Cognitive Radio system. Reconfigurable antenna is an antenna designed that is capable of changing its operating frequency. However, th...
