RESOURCE ALLOCATION FOR OFDMA-BASED COGNITIVE RADIO NETWORKS WITH APPLICATION TO H.264 SCALABLE VIDEO TRANSMISSION

Resource Allocation for OFDMA-Based Cognitive Radio Networks with Application to H.264 Scalable Video Transmission

Resource allocation schemes for orthogonal frequency division multiple access- (OFDMA-) based cognitive radio (CR) networks that impose minimum and maximum rate constraints are considered.To demonstrate the practical application of such systems, we consider the transmission of scalable video sequences.An integer programming (IP) formulation of the
