本文介绍话音插空技术应用于数字电话中的二种方案:一是以沃尔什函数作载波,利用话音插空技术的自适应多路增量调制的方法;另一是在ΔM/TDM复用方式中引入数字话音插空技术的方法。
This article introduces two kinds of schemes that the voice plugging technology is used in digital telephones: one is the adaptive multi-channel incremental modulation method using the Walsh function as the carrier and the voice plugging technology; the other is that in the ΔM / TDM complex The way to introduce digital voice insertion technology.
