Detailed Description¶

Allocate with despreader_create(). Embeds the carrier (car) and code (code) loops by value; the despreader owns the copied spreading code and the bit-sync histogram.

Public Attributes Documentation¶

variable bit_acc¶

double despreader_state_t::bit_acc;

running sum of Re(prompt) over the bit.

variable bit_phase¶

size_t despreader_state_t::bit_phase;

detected bit boundary (argmax flip_hist).

variable car¶

costas_state_t despreader_state_t::car;

carrier (Costas/FLL-assisted-PLL) loop.

variable code¶

dll_state_t despreader_state_t::code;

code (early/prompt/late DLL) loop.

variable code_copy¶

uint8_t* despreader_state_t::code_copy;

owned copy of the spreading code.

variable epoch_count¶

size_t despreader_state_t::epoch_count;

code periods processed so far.

variable epochs_in_bit¶

size_t despreader_state_t::epochs_in_bit;

periods accumulated in the current bit.

variable flip_hist¶

size_t* despreader_state_t::flip_hist;

prompt sign-flip histogram, length np.

variable have_prev¶

int despreader_state_t::have_prev;

prev_sign valid.

variable periods_per_bit¶

size_t despreader_state_t::periods_per_bit;

code periods per data bit (>=1).

variable prev_sign¶

int despreader_state_t::prev_sign;

previous prompt sign (+1/-1).

variable tlm_ctx¶

dp_tlm_t* despreader_state_t::tlm_ctx;

telemetry gate: non-NULL when the embedded loops are attached (despreader_set_telemetry); the probes live on car.tlm / code.tlm. Not serialized (field-wise triplet skips it).
