-
摘要: 本文给出了基于MSDE、LMSDE信号模型的信号编码的数学描述。把LMSDE信号模型的模拟信号编码过程转化为求解一个带非线性约束的二次规划问题并给出了SUMT外点法求解的方法。最后,通过两个例子说明了本文方法的有效性和高信噪比下对噪声的鲁棒性。Abstract: In this paper, the mathmetical description of signal coding based on MSDE and LMSDE model is given. The signal coding under LMSDE model is transformed into solving a quadratic programs with nonlinear constrains. Finally, the efficiency and robustness under high SNR are shown by coding to two signals.
