Hi guys,
Recently, I have conducted a project based on ofdm benchmark. However, when I use the high modulation rate like qam16 and qam64, the packet error rate increase significantly. I guess the reason is that the preamble in gunradio is too weak to do channel estimation, thereby raising the packet error rate.
Furthermore, even though I test the example offline without going through the channel, the packet error rate still very high, which make me feel confused. It is supposed to perform normally offline, without any decoding error right?
Best,
Kay
