Systems and methods for including an identifier with a packet associated with a speech signal
摘要：
A method for including an identifier with a packet associated with a speech signal is described. A signal is received. The signal is partitioned into a plurality of frames. A frame of the signal is encoded into a packet. A determination is made if the packet is encoded as a wideband packet or a narrowband packet. An identifier is packed in the packet based on the determination. The packet is transmitted. At least two illegal values are provided from an N-bit parameter, wherein at least one bit from the N-bit parameter is used to carry information. A number of bits from the N-bit parameter that are used to carry information is equal to log2(X), wherein X is the number of illegal values provided from the N-bit parameter.

描述了一种用于包括与语音信号相关联的分组的标识符的方法。 接收到一个信号。 信号被分割成多个帧。 信号的帧被编码成一个数据包。 如果分组被编码为宽带分组或窄带分组，则确定。 基于确定将标识符打包在分组中。 数据包被传输。 从N比特参数提供至少两个非法值，其中来自N比特参数的至少一个比特用于携带信息。 来自用于传送信息的N位参数的位数等于log2（X），其中X是从N位参数提供的非法值的数量。
