  Pulsars are known to manifest complex phenomena, such as nulling, sub-pulse
drifting, and periodicity. Within the purview of this investigation, we have
harnessed the wavelet analysis technique to scrutinize the multifaceted
periodicities and sub-pulse drifting characteristics exhibited by PSR
J1926-0652, discovered by the Five-hundred-meter Aperture Spherical radio
Telescope (FAST). Our analysis draws upon the rich dataset acquired from the
FAST ultra-wide-bandwidth receiver (UWB), meticulously examining pulse
attributes encompassing an entire pulse. It is notable that the pulse apex
recurrently manifests approximately every 17.11 times the pulsar's period P,
individual sub-pulses exhibit a drifting phenomenon, with a phase decrement of
approximately $1.04^\circ$ over each P. Intriguingly, the central phase of each
sub-pulse track gradually increments over temporal evolution. Furthermore, the
relative offset distribution between successive sub-pulse tracks emanating from
the trailing and leading components remains comparatively stable, with a
central tendency of approximately $\sim$6.87$\pm$2.56 P. Most notably, derived
from the outcomes of wavelet analysis, we ascertain a negative correlation of
-0.98 between the periods of sub-pulses and their drifting rates, alongside the
intrinsic period of sub-pulses identified at 28.14 seconds.
