Hello, I'd like to calculate the complex dot product with GNU Radio.
Is there a way to do it faster that this? This correlation takes "ages"... --- snipp --- // calculates the inner product <a, b> between complex vectors (dot // product), optionally shifts vector b first. gr_complex ofdm_rx_cc::dot_prod(gr_complex* a, gr_complex* b, unsigned int len, int shift) { gr_complex cor; assert((unsigned int)abs(shift)<len); if (shift<0) { return conj(dot_prod(b, a, -shift)); } b=b+shift; for(unsigned int i=0; i<(len-shift); i++) { cor+=a[i]*conj(b[i]); } return cor; } --- snipp -- Jens _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
