lf_reset
Reset the current phase (and optionnaly frequency) of a loop filter object.
Calling sequence
lf = lf_reset(lf, phi);
lf = lf_reset(lf, phi, nu);
lf = lf_reset(lf, phi); lf = lf_reset(lf, phi, nu);
Parameters
- lf:
Loop filter object
- phi:
Initial phase, in radians
- nu:
Initial frequency, normalized to sampling frequency (note: only applicable to a second order loop filter)
Loop filter object
Initial phase, in radians
Initial frequency, normalized to sampling frequency (note: only applicable to a second order loop filter)
Description
This function can be used for example just after initial phase and frequency estimation in a data preamble.
