In numerous applications, such as communications, audio and music technology, speech coding and synthesis, antenna and transducer arrays, and time delay estimation, not only the sampling frequency but the actual sampling instants are of crucial importance. Digital fractional delay (FD) filters provide a useful building block that can be used for fine-tuning the sampling instants, i.e., implement the required bandlimited interpolation. In this paper an overview of design techniques and…

Distortion Reduction in Fractional Delay Filters

The cause of head distortion is identified and a solution to this problem for reducing the overall distortion in FD filters is proposed, using relative root-mean-square (RMS) error as a metric to quantify the overall difference between the frequency-domain response of an FD filter and the ideal one.

This work treats some aspects of multi-carrier modulation (MCM) and single-carrier frequency-domain equalization (SC-FDE), which are closely related block transmission schemes. In both cases, the

Offset windowing for FIR fractional-sample delay

Non-optimal FIR filters used for fractional-sample delay, despite their wideband nature, are shown to benefit significantly from application of windowing, particularly if they are cast as asymmetric modifications of their conventional forms.

Optimal two-term offset windowing for fractional delay

Fractional-sample delay in discrete-time systems is often provided by special FIR filters which are asymmetric about mid-sequence. Here we preserve the appeal of sine-sequence fractional delayers

An approach for the design of fractionally shifted (asymmetric) windows is presented, based on bandlimited sinc interpolation combined with oversampling techniques, demonstrating that shifting of symmetric windows can be achieved while essentially maintaining the magnitude response of the window spectrum.
