WitrynaExact closed-form expressions for the outage probability (OP) of two NOMA secondary destination users (U 1 and U 2 ) are derived in the case of imperfect channel state information. Then, we find optimal power allocation factors for different distances of U 1 to satisfy the OP fairness for both users. Witryna13 kwi 2024 · We also generalize the framework to an imperfect CSI case where the additional interference term due to incomplete interference cancellation is considered, and the nonconvex robust MSE minimization problem is solved by a proposed inexact block coordinate descent algorithm.
