-
摘要: 本文給出了基于MSDE、LMSDE信號模型的信號編碼的數(shù)學(xué)描述。把LMSDE信號模型的模擬信號編碼過程轉(zhuǎn)化為求解一個帶非線性約束的二次規(guī)劃問題并給出了SUMT外點法求解的方法。最后,通過兩個例子說明了本文方法的有效性和高信噪比下對噪聲的魯棒性。

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. -
