AGC bandwidth as a fraction of the slowest loop; see mpsk_rx_agc_bn().

variable bn_carrier¶

double mpsk_rx_loops_t::bn_carrier;

carrier loop noise bandwidth (per symbol).

variable car_error¶

double mpsk_rx_loops_t::car_error;

last carrier phase discriminator (stress).

variable car_lf¶

loop_filter_state_t mpsk_rx_loops_t::car_lf;

2nd-order carrier PI loop.

variable car_lock¶

lockdet_state_t mpsk_rx_loops_t::car_lock;

de-chattered binary carrier lock.

variable differential¶

int mpsk_rx_loops_t::differential;

bits(): differential demap.

variable freq_ctrl¶

double mpsk_rx_loops_t::freq_ctrl;

carrier command now applied, cycles/sample at the LO's own rate.

variable freq_scale¶

double mpsk_rx_loops_t::freq_scale;

loop-filter output -> freq_ctrl; rad/symbol to cycles per LO sample, set once at init.

variable have_prev_idx¶

int mpsk_rx_loops_t::have_prev_idx;

differential: prev_idx valid.

variable lo_sps¶

double mpsk_rx_loops_t::lo_sps;

samples per symbol at the LO's own rate.

variable lock¶

double mpsk_rx_loops_t::lock;

EMA of the carrier lock signal.

variable lock_time¶

int64_t mpsk_rx_loops_t::lock_time;

sym_count when carrier lock was first declared, or -1 if never. Running state.

variable m¶

int mpsk_rx_loops_t::m;

constellation order M (2, 4, 8).

variable m_out¶

size_t mpsk_rx_loops_t::m_out;

terminal outputs per symbol.

variable prev_idx¶

unsigned mpsk_rx_loops_t::prev_idx;

differential: prev sliced index.

variable sps¶

double mpsk_rx_loops_t::sps;

samples per symbol at the receiver's input.

variable sym_count¶

size_t mpsk_rx_loops_t::sym_count;

symbols emitted; also dates lock_time.

variable sym_rot¶

float _Complex mpsk_rx_loops_t::sym_rot;

exp(j*phi0): NDA grid -> slicer.

variable timing¶

ratesync_loop_t mpsk_rx_loops_t::timing;

the shared timing loop -> rate_ctrl.

variable tlm¶

mpsk_rx_tlm_t mpsk_rx_loops_t::tlm;

live attachment; zeroed in state blobs.

variable zeta¶

double mpsk_rx_loops_t::zeta;

damping factor for both loops.
