Yong Ching Lim, Chaogeng Huang, Gang Li, Hong Bo Xu, Anthony George Constantinides · 2013
This paper presents an approach for digital lattice filter roundoff noise reduction using error spectrum shaping (ESS). ESS roundoff noise expression for the one-, two-, three-, and four-multiplier lattice structures are derived. A numerical example for demonstrating the performance of the proposed ESS noise reduction in lattice filters is also presented.
