Devin, The metadata is already passed to GNURadio by the USRP2 firmware. Its the gnuradio usrp2 source block that doesn't do anything with this information (metadata has the timestamp for the first sample of each frame) You can modify the code to provide a second stream, or interleave the data wi

I will explain the RX side, the TX side is basically the same. small_hb_dec is the short filter which works at the higher rate. There are 2 of them instantiated, one for I and one for Q. It has 7 taps. One of those taps is the center tap which only requires a shift and not a multiply, and 2

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 (b
