Struct mpsk_receiver_state_t¶

ClassList > mpsk_receiver_state_t

M-PSK receiver state. More...

• #include <mpsk_receiver_core.h>

Public Attributes¶

Detailed Description¶

Allocate with mpsk_receiver_create(). Embeds the carrier loop (car) and symbol-timing loop (sync) by value and owns the matched-filter FIR; the carrier NCO and lock metric live in car. Treat all fields as internal (use the getters); they are exposed for the inline sample loop.

Public Attributes Documentation¶

variable auto_handover¶

int mpsk_receiver_state_t::auto_handover;

opt-in NDA->decision handover.

variable car¶

carrier_nda_state_t mpsk_receiver_state_t::car;

carrier loop: wipe NCO + arm I/D + NDA.

variable differential¶

int mpsk_receiver_state_t::differential;

bits(): differential demap.

variable have_prev_idx¶

int mpsk_receiver_state_t::have_prev_idx;

differential: prev_idx valid.

variable lock_thresh¶

double mpsk_receiver_state_t::lock_thresh;

handover lock-metric threshold.

variable m¶

int mpsk_receiver_state_t::m;

constellation order M (2, 4, 8).

variable mf¶

fir_state_t* mpsk_receiver_state_t::mf;

matched filter on the de-rotated stream.

variable mf_taps¶

float* mpsk_receiver_state_t::mf_taps;

owned real MF taps.

variable n¶

int mpsk_receiver_state_t::n;

arm dumps per symbol.

variable prev_idx¶

unsigned mpsk_receiver_state_t::prev_idx;

differential: prev sliced index.

variable pulse¶

int mpsk_receiver_state_t::pulse;

MPSK_RX_PULSE_IANDD / _RRC.

variable rrc_beta¶

double mpsk_receiver_state_t::rrc_beta;

RRC roll-off (pulse == RRC).

variable rrc_span¶

int mpsk_receiver_state_t::rrc_span;

RRC one-sided span, symbols.

variable sps¶

size_t mpsk_receiver_state_t::sps;

samples per symbol.

variable sym_count¶

size_t mpsk_receiver_state_t::sym_count;

symbols emitted (warmup counter).

variable sym_rot¶

float complex mpsk_receiver_state_t::sym_rot;

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

variable sync¶

symsync_state_t mpsk_receiver_state_t::sync;

Gardner symbol-timing loop (by value).

variable tracking¶

int mpsk_receiver_state_t::tracking;

0 = NDA acquire, 1 = decision.

variable warmup_syms¶

size_t mpsk_receiver_state_t::warmup_syms;

symbols before handover allowed.
