Hello,
Just another question concerning the file "gr_mpsk_receiver_cc.cc".
In the extract of code below, why are phase_error_detector_generic and
decision_generic used for all BPSK, QPSK and other modulations?
Have optimized algorithms for BPSK and QPSK already been implemented?
// Select a phase detector and a decision maker for the modulation
order
switch(d_M) {
case 2: // optimized algorithms for BPSK
d_phase_error_detector =
&gr_mpsk_receiver_cc::phase_error_detector_generic; //bpsk;
d_decision = &gr_mpsk_receiver_cc::decision_generic; //bpsk;
break;
case 4: // optimized algorithms for QPSK
d_phase_error_detector =
&gr_mpsk_receiver_cc::phase_error_detector_generic; //qpsk;
d_decision = &gr_mpsk_receiver_cc::decision_generic; //qpsk;
break;
default: // generic algorithms for any M (power of 2?) but not pretty
d_phase_error_detector =
&gr_mpsk_receiver_cc::phase_error_detector_generic;
d_decision = &gr_mpsk_receiver_cc::decision_generic;
break;
