GFSK link performance
Hi everyone, I would like to ask if anyone has done some experiments with the GFSK mod/demod block provided by GNU Radio? My link works fine from SNR = 12 dB, but if 1-2 dB below that, the behavior is quite strange. I mean the received file will occasionally have 1-2 payload with BER ~0.4 or 0.5, while all the rest payload still has BER ~0.
Is there any problem with the default GFSK demod block of GNU Radio? Thank you.
