In this paper, a novel co-design scheme of TOD protocol and H∞ filter for the NCS subject to communication constraints is investigated. Firstly, the closed-loop NCS with network-induced imperfections is modeled as a discrete-time switched system with uncertain parameters. Then a sufficient condition is proposed for exponential stability of the NCS through using the average dwell time method of switched...
A bandpass delta-sigma modulator with a widely tunable center frequency range for direct digitization of IF or RF signals can be a key building block for highly digitized radio receivers. The performance of the bandpass modulator is highly dependent on the accuracy of the noise transfer function zero locations in the presence of process spread. An automatic calibration method is proposed to calibrate...
Based on the principle of Fourier analysis, the coefficients within space domain in Mallat wavelet filter are solved by MATLAB programming tool, and the foundation for the application of Mallat wavelet basis is established.
