This paper is concerned with the asymptotic stability analysis of linear systems with signalquantization and state observation.
针对基于状态观测和信号量化的线性系统,进行了稳定性分析与研究。

At first, it quantizes the image coefficient vector gotten from DWT with the lattice vector quantization technology, then imbeds the watermark signal into the coefficient.
In multimedia signal processing, quantization error is a function of input signal and it results in the audible distortion and noise modulation in the audio signals.
