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。
This paper presents a mathematical description of signal coding based on the MSDE and LMSDE signal models. The simulation signal coding process of LMSDE signal model is transformed into solving a quadratic programming problem with nonlinear constraints and a method of solving the SUMT external point method is given. Finally, two examples are given to illustrate the effectiveness of the proposed method and the robustness against noise under high SNR.
