Public Attributes Documentation¶

variable base_inc¶

uint32_t symsync_state_t::base_inc;

nominal NCO inc (one wrap / symbol).

variable bn¶

double symsync_state_t::bn;

loop noise bandwidth (retained).

variable farrow¶

farrow_state_t symsync_state_t::farrow;

fractional interpolator.

variable have_ontime¶

int symsync_state_t::have_ontime;

a previous on-time sample exists.

variable last_error¶

double symsync_state_t::last_error;

last Gardner timing error.

variable lf¶

loop_filter_state_t symsync_state_t::lf;

2nd-order timing PI loop.

variable mid¶

float complex symsync_state_t::mid;

mid-symbol interpolant (Gardner).

variable prev_ontime¶

float complex symsync_state_t::prev_ontime;

previous on-time interpolant.

variable pwr_avg¶

double symsync_state_t::pwr_avg;

running symbol power (TED normaliser).

variable rate_est¶

double symsync_state_t::rate_est;

smoothed tracked samples/symbol.

variable sps¶

size_t symsync_state_t::sps;

nominal samples per symbol.

variable timing¶

nco_state_t symsync_state_t::timing;

integer timing NCO (phase/phase_inc).

variable zeta¶

double symsync_state_t::zeta;

damping factor (retained).
