“…Interpolation for symbol timing recovery shown in Fig. l(a) was proposed in [2,3] and is suitable for all-digital implementation where Nyquist rate sampled input signals are available. Due to the widespread use of oversampling in digital communications (see Section II), the interpolation method for timing recovery shown Fig.…”

It is advantageous to use oversampling techniques with either AX or broadband data converters in both wireline and wireless digital receivers. This paper discusses the oversampling techniques for all-digital implementation of symbol timing recovery in digital receivers. The idea of oversampling techniques for timing recovery is to adjust the timing phases while decimating the oversampled signals. The spurious signal introduced by adjusting the CIC's (cascaded integrator-comb) timing phase has been analyzed and was found to be a serious problem. In this paper, a dual-differentiator timing phase adjustable decimation filter has been proposed and was used for symbol timing recovery. Simulations were provided to verify the validity of the proposed method.
