Functor for calculating the autocorrelation given a PSD.

Stores the fftT object and related working memory so that repeated calls do not re-allocate or re-plan the FFT.

Template Parameters

T	is the real type of the PSD and resultig A.C.

◆ operator()() [1/2]

template<typename T >

void mx::sigproc::autocorrelationFromPSD< T >::operator()	(	std::vector< T > &	ac,
		std::vector< T > &	psd
	)

inline

Calculate the A.C. as the inverse FFT of the PSD.

This calculates the circular autocorrelation from the PSD.

Parameters

[out]	ac	On output contains the autocorrelation. If ac.size()==0, it is allocated to psd.size().
[in]	psd	the 2-sided FFT storage order PSD

template<typename T >

void mx::sigproc::autocorrelationFromPSD< T >::operator()	(	T *	ac,
		size_t	Nac,
		T *	psd,
		size_t	Npsd
	)

inline

Calculate the A.C. as the inverse FFT of the PSD.

This calculates the circular autocorrelation from the PSD.

Parameters

[out]	ac	pre-allocated array, on output contains the first Nac points of the autocorrelation
[in]	Nac	the allocated size of ac.
[in]	psd	the 2-sided FFT storage order PSD
[in]	Npsd	the number of points in the PSD
