Public Attributes Documentation¶

variable buf¶

float complex* ppe_state_t::buf;

windowed, dechirped, zero-padded input, nfft.

variable drate¶

double ppe_state_t::drate;

chirp-rate grid step.

variable fft¶

fft_state_t* ppe_state_t::fft;

forward plan, size nfft.

variable mag¶

float* ppe_state_t::mag;

dB magnitude scratch, nfft.

variable max_len¶

size_t ppe_state_t::max_len;

max input length (sizes the plan/scratch).

variable max_rate¶

double ppe_state_t::max_rate;

chirp-rate search half-span (cycles/sample^2).

variable n_rate¶

size_t ppe_state_t::n_rate;

number of chirp-rate hypotheses (1 if max_rate=0).

variable nfft¶

size_t ppe_state_t::nfft;

zero-padded transform length (next pow2 of max_len).

variable rowfrq¶

double* ppe_state_t::rowfrq;

per-rate winning frequency, n_rate.

variable rowpk¶

double* ppe_state_t::rowpk;

per-rate winning peak dB, n_rate.

variable spec¶

float complex* ppe_state_t::spec;

FFT output, nfft.

variable win¶

float* ppe_state_t::win;

window scratch, max_len.
