—In this paper, the capacity of multiple input multiple output-orthogonal frequency division multiplexing (MIMOOFDM) systems is analyzed under doubly correlated fading channels. ...
— The increase in the demand for voice and data wireless services creates a need for a more efficient use of the available bandwidth. Current and future generations cellular sys...
It has been known how to use computational fixed point theorems to verify existence and uniqueness of a true solution to a nonlinear system of equations within a small region abou...
This paper addresses a method of blind source separation that jointly exploits the nonstationarity and temporal structure of sources. The method needs only multiple time-delayed co...
