[Discuss-gnuradio] Interference-alignment and Coordinated multi-point on USRP

Re: [Discuss-gnuradio] dynamically changing delay in gr_delay (or history in any gr_block)

I can confirm that if my FIR taps are defined as: (0,)*delay+(1,)+(0,)*(19-delay) then i can change the delay dynamically for any values between 0 and 19 in the grc file that i sent earlier (attached here as well) EVEN without the second (trivial) FIR filter present! So it is clearer now that th

More in general, is there a reason why the CPM modulator in the gr-digital package generates its own filter taps instead of using the functions in gr_cpm? Also, it seems that gr_cpm has other filters implemented through the phase_response function that belong in gr_firdes (which I assume stands
