Abstract
Fractional delay (FD) filter is widely used in digital receiver for time-domain interpolation, such as for compensating sampling clock offset (SCO). Thiran IIR filter is an FD all-pass filter that can retain excellent frequency response. This paper presents an low-complexity implementation of the Thiran filter with application to the sampling clock offset compensation block in digital communication receivers.
