Constructor & Destructor Documentation

gri_fft_filter_ccc_generic::gri_fft_filter_ccc_generic	(	int	decimation,
		const std::vector< gr_complex > &	taps
	)

Construct an FFT filter for complex vectors with the given taps and decimation rate.

This is the basic implementation for performing FFT filter for fast convolution in other blocks for complex vectors (such as gr_fft_filter_ccc).

Parameters:

decimation	The decimation rate of the filter (int)
taps	The filter taps (complex)

Member Function Documentation

int gri_fft_filter_ccc_generic::filter	(	int	nitems,
		const gr_complex *	input,
		gr_complex *	output
	)

Perform the filter operation.

Parameters:

nitems	The number of items to produce
input	The input vector to be filtered
output	The result of the filter operation

int gri_fft_filter_ccc_generic::set_taps

(

const std::vector< gr_complex > &

taps

)

Set new taps for the filter.

Sets new taps and resets the class properties to handle different sizes

Parameters:

taps	The filter taps (complex)
