Fast FFT filter with gr_complex input, gr_complex output and gr_complex taps.


Constructor & Destructor Documentation

gr::filter::kernel::fft_filter_ccc::fft_filter_ccc ( int  decimation,
const std::vector< gr_complex > &  taps,
int  nthreads = 1 
)

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 fft_filter_ccc).

Parameters:
decimationThe decimation rate of the filter (int)
tapsThe filter taps (complex)
nthreadsThe number of threads for the FFT to use (int)
gr::filter::kernel::fft_filter_ccc::~fft_filter_ccc ( )

Member Function Documentation

int gr::filter::kernel::fft_filter_ccc::filter ( int  nitems,
const gr_complex input,
gr_complex output 
)

Perform the filter operation.

Parameters:
nitemsThe number of items to produce
inputThe input vector to be filtered
outputThe result of the filter operation
int gr::filter::kernel::fft_filter_ccc::nthreads ( ) const

Get number of threads being used.

void gr::filter::kernel::fft_filter_ccc::set_nthreads ( int  n)

Set number of threads to use.

int gr::filter::kernel::fft_filter_ccc::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:
tapsThe filter taps (complex)
