Recently, a wideband spectrum sensing scheme referred to as multiband joint detection has been proposed by Quan et al., in which a set of frequency dependent detection thresholds are optimized to achieve the best trade-off between aggregate measures of opportunistic throughput and interference to primary users in cognitive radio (CR) networks. While this scheme shows significant performance gains...
In this paper, a frequency-coupled optimum linear energy combiner (OLEC) structure, recently proposed for single user scenarios, is generalized to multiple users and integrated into the spatial-spectral joint detection framework introduced by Quan <etal/>, to take further advantage of subband occupancy correlation in cooperative wideband spectrum sensing. In particular, the design of the detection...
