Hi I can help a bit with the implementation of the one HBF. It has 31taps, of which every second one, apart from the center one is zero. the center one is scaled relative to one (2^18 on the FPGA). In total there is therefore (16+the center one) non-zero taps. This requires 8 multiplications (because of the symmetry, we can simply add the 1st and 31st,3rd and 29th values,etc. and then multiply by the appropriate tap value. For the center tap,we just need to bit-shift the sample at that position appropriately.
Hope this helps a bit. Sebastiaan _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
