I was looking back over the Quadrature Demod code and I happened to notice something unusual. The call to the Volk multiply conjugate routine appears to use in[noutput_items+1] on the last calculation.
Here's the call: volk_32fc_x2_multiply_conjugate_32fc(&tmp[0], &in[1], &in[0], noutput_items); It obviously works correctly, and the buffer's bigger than noutput_items so it doesn't seem to cause a memory access issue. So my question is: when volk uses the memory at in[noutput_items+1] what value is it using? Is it using a zeroed byte, something from a history buffer, or whatever happened to be there? Would anyone have any insight? Thanks! _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
