A stable adaptive structure for delta modulation with improved performance
نویسندگان
چکیده
In this paper, we propose and study an adaptive delta modulator that has improved SNR performance and better robustness in tracking highly varying signals. The step-size adaptation used in this modulator is based on information about the absolute value of the quantizer input. The modulator is shown to be free of zero-input limit cycles and is BIBO stable.

An Adaptive Structure for Sigma Delta Modulation with Improved Dynamic Range
This work proposes a novel structure for adaptive sigma delta modulation that leads to considerable improvement in the dynamic range of the modulator. The quantizer step-size is adapted based on estimates of the input signal to the quantizer block rather than on estimates of the input signal to the modulator itself, as is common in current schemes. The proposed structure can be implemented rath...
متن کاملA 2-bit Adaptive Delta Modulation System with Improved Performance
A 2-bit adaptive delta modulation system with improved performance is proposed in this paper. Its main characteristic is a new adaptation algorithm that incorporates both memory and look-ahead instantaneous step-size estimation and leads the modulator into generating a 2-bit output codeword. As shown by computer simulation results, the proposed system offers reduced overshoot and fast response ...
متن کاملModel-based predictive adaptive delta modulation
This paper presents a new technique in digital communications, called modelbased-predictive adaptive-delta-modulation (MBP-ADM). MBP-ADM uses system identification tools to identify a model of the signal which is used for prediction. The prediction helps the system to respond adaptively to a varying input signal, in order to achieve improved performance. The results show a substantial improveme...
متن کاملStability Analysis of an Adaptive Structure for Sigma Delta Modulation
In previous work [ 11, we have proposed an adaptive sigma delta modulator with improved dynamic range. The modulator adapts the step-size of the quantizer from estimates of the quantizer input. In this paper, we conduct a stability analysis of the new modulator.
