1-D FFT correlator state. More...

Public Attributes¶

Type	Name
float complex *	accum
size_t	count
size_t	dwell
fft_state_t *	fwd
fft_state_t *	inv
size_t	n
size_t	n_out
float complex *	ref_spec
float complex *	work_fft
float complex *	work_pad

Detailed Description¶

Allocate with corr_create(); never stack-allocate. ref_spec/work_fft/accum are each n complex floats; work_pad (n_out) exists only on the decoupled-inverse path.

Public Attributes Documentation¶

variable accum¶

float complex* corr_state_t::accum;

Coherent product-spectrum accumulator.

variable count¶

size_t corr_state_t::count;

Frames accumulated so far (0 … dwell-1).

variable dwell¶

size_t corr_state_t::dwell;

Integration depth; dump every dwell calls.

variable fwd¶

fft_state_t* corr_state_t::fwd;

Forward plan (sign = -1) at n.

variable inv¶

fft_state_t* corr_state_t::inv;

Inverse plan (sign = +1) at n_out.

variable n¶

size_t corr_state_t::n;

FFT / reference length (samples).

variable n_out¶

size_t corr_state_t::n_out;

Output length (== n unless decoupled).

variable ref_spec¶

float complex* corr_state_t::ref_spec;

conj(FFT(ref)), pre-computed at create.

variable work_fft¶

float complex* corr_state_t::work_fft;

Scratch: FFT(in) · ref_spec (product).

variable work_pad¶

float complex* corr_state_t::work_pad;

Zero-padded product, n_out (NULL native).
