Abstract

This paper proposes a Cognitive Radio testbed setup. A reconfigurable PIFA antenna has been designed and simulated in AWR MWO. Then from these a look up table of different modes have been constructed in Labview Software. Then energy detection algorithm for wideband spectrum sensing was implemented in Labview and using NI PXI Chassis and NI VST the whole set up was tested and verified. Output is shown as LED indication which is the required PIN Diode switching configuration for reconfiguring the PIFA Antenna so as to achieve new transmission mode.
