Computation of higher-order cross moments based on matrix multiplication

The demand for efficient architectural designs for fast computation of higher-order cross moments is becoming increasingly significant as these statistics grow in importance as a signal processing tool. In this paper, we present a new approach to the computation of third- and fourth-order cross moments based on matrix multiplication. The results presented in this paper has the advantage of putting cross moments computation in a form that can benefit from previous (and possibly future) work on architectural designs for matrix multiplication.
