https://github.com/gnuradio/gnuradio/blob/master/gr-dtv/lib/dvbt2/dvbt2_paprtr_cc_impl.ccEven though it uses Volk kernels extensively, it's performance is still lacking. Right now, it's capable of light PAPR reduction, but for heavier reduction, it's takes too much CPU and the transmitter flow goes non real-time.
The target performance would be a clipping value of 2.57 over 50 iterations, which is what is used in the Ofcom mode 2 profile. Current performance is a clipping value around 2.9 over 20 iterations (on my workstation).

Hi, for my thesis I'm making "porting" of gnuradio blocks over CUDA..For the moment,I've bring basick blocks,FIR filter,FFT,an FM receiver(not so good due to latency) and I'm working with ofdm..I still need to implement IIR filterWhich other blocks do you think that could be nice(useful,get performance,..) to bring over CUDA?Thanks for your opinions, marco
