    • An apparatus for demodulating an analogue input signal comprises a hard limiter stage (4) for converting the signal to a two level signal, A digital down converter/low pass filter stage (6) converts the signal to a base band signal, and a symbol synchronization stage (8) extracts symbol timing. An instantaneous phase detector (10) calculates the instantaneous phase of the one or more symbols associated with the input signal. If the input signal has been modulated according to a pi/4DQPSK, pi/2DBPSK, GMSK, or a GFSK modulation scheme, a differential detector (12) determines a difference in the phase between adjacent symbols, a coarse frequency offset compensation stage (14) applies a compensation signal to compensate for frequency offset, and a frequency offset estimation stage (16) updates this compensation signal. A demapper (18) generates a demodulated output signal after compensation by the frequency offset compensation stage.
    • 用于解调模拟输入信号的装置包括用于将信号转换为二电平信号的硬限幅器级(4),A数字下变频器/低通滤波器级(6)将信号转换为基带信号,以及符号 同步级(8)提取符号定时。 瞬时相位检测器(10)计算与输入信号相关联的一个或多个符号的瞬时相位。 如果输入信号已经根据pi / 4DQPSK,pi / 2DBPSK,GMSK或GFSK调制方案调制,则差分检测器(12)确定相邻符号之间的相位差,粗频率偏移补偿级(14 )施加补偿信号以补偿频率偏移,并且频率偏移估计级(16)更新该补偿信号。 解映射器(18)通过频率偏移补偿级在补偿后产生解调输出信号。
