Rate-Optimal and Reduced-Complexity Sequential Sensing Algorithms for Cognitive OFDM Radios
Sequential sensing algorithms are developed for OFDM-based hierarchical cognitive radio (CR) systems. Secondary users sense multiple subbands simultaneously for possible spectrum availabilities under hard misdetection constraints to prevent interference to the primary users. Accounting for the fact...
