The error signal is smoothed by loop filter, then it is used to change the control register of interpolator and decimator: The proposed algorithm can track the frequency shift of sampling clock. The algorithm is simulated in both AWGN and multipath fading channel.

这种方法在发送端相邻载波间采用差分QPSK调制，在接收端利用QPSK的差分解调信号获得同步误差信号，从而获得关于OFDM符号同步和采样钟同步调整的算法，其特点是无需专门的同步导频信号。

The digital/decimator filter samples and filters the modulator's stream of 1-bit codes and creates a slower multibit code.

SRC in SDR is also discussed, and two improved structures of CIC filter are presented. The first one is a CIC decimation filter based on polyphase structure and partially sharpening technique, which is suitable for the situation where the requirements in passband attenuation is not very high while the requirements in alias suppression and operating speed are relatively high. The other one is an improved CIC-Rotated Sinc decimator which possesses improved frequency response, low operating rate and low cost in hardware as well.
