[Discuss-gnuradio] CQPSK and raised cosine filters

[Rick Parrish]

Is anyone out there working one these?

1. CQPSK
2. raised cosine (or root-raised cosine) filters

I've got a working clock pulse recovery PLL for CQPSK but I'm wondering 
if running the data through a raised cosine filter will improve S/N for 
the final decoded result. The application is APCO Project 25 two-way 
voice communications.
