摘要

PPROBLEM TO BE SOLVED: To provide a discontinuous transmission bit processing method for a multirate modulation scheme for transmitting discontinuous transmission bits by defining an average value of I and Q signal axes as an allocation signal to a signal set fixedly having remaining bit values except for an inserted DTX bit. PSOLUTION: The DTX bit of the multirate modulation scheme is processing by successively performing steps of: receiving an input of a signal; deciding presence/absence of the DTX bit in the input signal; detecting a signal point where the remaining bits excluding the DTX bit from an IQ plane are similar when the DTX bit is present in the input signal; mapping a signal to a predetermined signal point S based upon the detected signal point; and transmitting the signal at a power level of the corresponding signal point.

要解决的问题：提供一种用于多速率调制方案的不连续传输位处理方法，该方法用于通过将I和Q信号轴的平均值定义为对固定地设置有剩余位值的信号的分配信号来传输不连续传输位除了插入的DTX位。解决方案：通过连续执行以下步骤来处理多速率调制方案的DTX位：接收信号的输入;确定输入信号中是否存在DTX位;当输入信号中存在DTX位时，检测从IQ平面中除DTX位之外的其余位相似的信号点;根据检测到的信号点将信号映射到预定信号点S;以相应信号点的功率电平发送信号。
