MELP vocoders utilize mixed pulse and noise as the excitation to elimate the buzzes in traditional LPC vocoders, and add a jitter voicing state to overcome the tonal noise.

MELP声码器采用混合脉冲和噪声激励解决了经典LPC的嗡嗡声的问题； 引入了抖动浊音状态以克服音调噪声；

According to a new type of mixed pulse compression signal, this paper discusses the mathematical expression, the way of processing and the expression of the ambiguity function.

提出一种由线性调频与二相码组合而成的新型混合脉冲信号，给出了其数学表达式、处理方法及其模糊函数的表达式。

I'm also back bartending and, mixed in with the grief, I can feel the pulse still there.
