A comparison of regularizations for an ill-posed problem
Abstract. We consider numerical methods for a “quasi-boundary value” regularization of the backward parabolic problem given by ut + Au = 0 , 0 < t < T u(T ) = f, where A ...

Sum Rate Maximization using Linear Precoding and Decoding in the Multiuser MIMO Downlink
Abstract--We propose an algorithm to maximize the instantaneous sum data rate transmitted by a base station in the downlink of a multiuser multiple-input, multiple-output system. T...
