Abstract :
This paper presents a heuristic averaging method for approximating a single-input single-output FIR digital block matrix filter (BMF) h by a structurally constrained BMF h˜ in order to exploit computational efficiency of the matrix implementation of convolution. The unique properties of the method are derived and applied to the circulant and Toeplitz matrix structures. Advantages and limitations of the method are considered. Simulations are submitted and discussed
