A Perturbation Theory On Statistical Quantization Effects In Fixed-Point Dsp With Non-Stationary Inputs |
Abstract | ||
|---|---|---|
A quantitative characterization of statistical quantization effects in a discrete-time digital system is derived as a function of fixed-point data types. The analysis is based on a perturbation theory approach which assumes the quantization noise is a small deviation from the ideal characteristics and that the system does not contain decision-error propagation. The theory works for both linear and nonlinear digital systems with either stationary or non-stationary inputs. The approach is applied to an LMS adaptive filter in both the transient and steady state periods. |
