cognitive radio was introduced as a promising technology to solve the inefficiency of spectrum utilization in this paper a cognitive radio network with mulitple amtennas and mutiple bands is configured as a non -cooperative game the underlay paradigm has been considered wherein secondary users equipped with cognitive radio can use the spectrum without violating interference constraints with primary users a new algorithm is proposed for solving the optimization problem. introduction of a diagonal block pricing factor matrix for each secondary link is the key idea of the proposed algorithm . two iterative algorithms are proposed jacobi and guass -sedel algorithms and their performance are evaluated.
