I need some understanding of what reasonably achievable sample rates are using GNU Radio to implement a packet base radio.
For example, I'm running into D's at only 430 k/samples. This is running a packet detecting radio using bpsk.
Those who have working OFDM radios, what sample rates does your system support without over/underflow? How about those with QPSK radios detecting packets, what samle rate can you support?
I'm not using a multi-rate approach, so I know there are gains to be had in my design. But for a BPSK radio with packet detection (and full synchronization), I'm surprised I'm hitting the low limits of what the USRP requires already.
