The primary objective of this paper is to establish
a generalized framework for pulse-shaping on the delay-Doppler
plane. To this end, we classify delay-Doppler pulse-shaping techniques into two types, namely, circular and linear pulse-shaping.
This paves the way towards the development of a generalized
pulse-shaping framework. Our generalized framework provides
the opportunity to compare different pulse-shaping techniques
under the same umbrella while bringing new insights into their
properties. In particular, our derivations based on this framework
reveal that the recently emerged waveform orthogonal delay-
Doppler multiplexing (ODDM) is a linear pulse-shaping technique. By presenting ODDM under our generalized framework,
we clearly explain the observed staircase behavior of its spectrum
which has not been previously reported in the literature. Another
contribution of this paper is the proposal of a simple out-of-band (OOB) emission reduction technique by inserting a small
number of zero-guard (ZG) symbols along the delay dimension
of the circularly pulse-shaped signals. Additionally, inserting
the zero-guards improves the bit-error-rate (BER) performance
of both circular and linear pulse-shaping techniques. Finally,
our simulation results confirm the validity of our mathematical
derivations, claims and the effectiveness of the ZGs in OOB
reduction and BER performance improvement.
