Two elements diversity planar antenna for a multiple-input multiple-output application is proposed. By adopting two Y-shaped radiators, the antenna provides wideband impedance matching characteristic over the desired frequency band. To reduce the

Multiple input multiple output techniques combined with orthogonal frequency division multiplexing (MIMO-OFDM) provide a promising approach for wireless systems. However, a serious drawback of the OFDM system is the high peak-toaverage power

This paper proposes a novel, highly effective spectrum sensing algorithm for cognitive radio and white space applications. The proposed spectral covariance sensing (SCS) algorithm exploits the different statistical correlations of the received
