Preetha Basu, R. Gopikakumari . Sparse Matrix based Computational Overhead Reduction in UMRT for N a power of 2. International Journal of Computer Applications. 75, 8 ( August 2013), 32-38. DOI=10.5120/13133-0502
Abstract
Unique Mapped Real Transform (UMRT) is a transform which helps in frequency domain analysis of signals in the real domain. Different algorithms are developed for the computation of the unique MRT coefficients for N a power of 2 and for N an even number. They identify and place the UMRT coefficients in the form of an UMRT matrix. The basis matrices of this transform are observed to be sparse in nature. In this paper a new technique is proposed to reduce the computational overhead in UMRT, the size N being a power of two, exploiting the sparse nature of the basis matrices.
