Model-based predictive adaptive delta modulation

چکیده
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 improvement in the signal to noise ratio (SNR) with MBP-ADM’s compared to the ‘classical adaptive’ and ‘nonadaptive’ Delta Modulators.

متن کاملA stable adaptive structure for delta modulation with improved performance
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.
