Method and device for efficient in-band dim-and-burst signaling and half-rate max operation in variable bit-rate wideband speech coding for CDMA wireless systems
Abstract:
In the method and device for interoperating a first station using a first communication scheme and comprising a first coder and a first decoder with a second station using a second communication scheme and comprising a second coder and a second decoder, communication between the first and second stations is conducted by transmitting signal-coding parameters related to a sound signal from the coder of one of the first and second stations to the decoder of the other station. The sound signal is classified to determine whether the signal-coding parameters should be transmitted from the coder of one station to the decoder of the other station using a first communication mode in which full bit rate is used for transmission of the signal-coding parameters. When classification of the sound signal determines that the signal-coding parameters should be transmitted using the first communication mode and when a request to transmit the signal-coding parameters from the coder of one station to the decoder of the other station using a second communication mode designed to reduce bit rate during transmission of the signal-coding parameters is received, a portion of the signal-coding parameters from the coder one station is dropped and the remaining signal-coding parameters are transmitting to the decoder of the other station using the second communication mode. The dropped portion of the signal-coding parameters are regenerated before the decoder of the other station decodes the signal-coding parameters.
Abstract(Chinese):

在用于使用第一通信方案互操作第一站的方法和设备中，包括第一编码器和具有第二站的第一解码器，并且包括第二编码器和第二解码器，第一和第二站之间的通信 通过将与来自第一和第二站中的一个的编码器的声音信号相关的信号编码参数发送到另一站的解码器来进行。 声音信号被分类以确定信号编码参数是否应当使用全位比特率用于传输信号编码参数的第一通信模式从一个站的编码器发送到另一站的解码器。 当声音信号的分类确定应当使用第一通信模式发送信号编码参数时，以及当使用第二通信模式从一个站的编码器向另一站的解码器发送信号编码参数的请求时 被设计为在信号编码参数的传输期间降低比特率被接收到，来自编码器一个站的信号编码参数的一部分被丢弃，剩下的信号编码参数使用第二个信号编码参数传送到另一台的解码器 通讯模式。 信号编码参数的丢弃部分在另一站的解码器解码信号编码参数之前被再生。
