This Springer Brief investigates spectrum sharing with limited channel feedback in various cognitive radio systems, such as point-to-point, broadcast scheduling and ad-hoc networks. The design aim is to optimally allocate the secondary resources to improve the throughput of secondary users while maintaining a certain quality of service for primary users. The analytical results of optimal resource allocation are derived via optimization theory and are verified by the numerical results. The results demonstrate the secondary performance is significantly improved by limited feedback and is further improved by more feedback bits, more secondary receivers and more primary side information.

Wei Zhang received his Ph.D. degree from The University of Texas Graduate School of Biomedical Sciences. He joined the faculty of M. D. Anderson Cancer Center in 1994 where he is currently an Associate Professor and the Director of the Cancer Genomics Core Laboratory. Dr. Zhang's research programs include cancer genomics and informatics, tumor suppressor genes, and signal transduction studies. Dr. Zhang is an Associate Editor for American Association of Cancer Research journal Clinical Cancer Research, and serves on editorial board of journals Cancer Biology and Therapy, Histology and Histopathology, International Journal of Oncology, BMC Genomics, Technology in Cancer Research and Treatment, and Molecular Cancer.
