Sub-carrier efficient resource allocation for MIMO-OFDMA based cognitive radio / Mohd Zahir Md Kassim

Orthogonal Frequency Division Multiple Access (OFDMA) is the access techniques used in Cognitive Radio (CR). By assigning subset Resource Allocation (RA) of subcarrier to individual user, the multiple accesses are achieved in OFDMA whereby low data rate transmission from several users is allowed. Th...
