We present a FRFT high-resolution computation (zoom-FRFT) method
which can zoom-in on any interested portion of fractional spectrum by setting spectrum range and output number
M
.In addition
for solving lower efficiency of zoom-FRFT for small
M
a FRFT single-point fast computation (SP-FRFT) method based on Horner rule is presented and its further reduction is made for zero-point computation.It can be used to increase computational efficiency for small M
