Re: [Discuss-gnuradio] IEEE 802.11 receiver not working for high sampling rates

Hi, As Marcus suggested, I put a frequency sink directly to the receiver to look at the signal. Both at 1 MHz and 10 MHz the signal is noisy. The power is around -120 to -100 db. However, in the case of 1 MHZ all packets sent by the USRP transmitter are received correctly with almost negligible pa

Hi, well, the next step here would pretty clearly be going through the flow graph and finding out where things don't work – you'd typically start with something like a frequency or waterfall plot directly at the receiver, and then look for packet errors, and so on. Use a Qt time sink to look for c

Hi, I am working with USRPs N210 and GNU Radio version 3.7. I wasn't able to work with higher sampling rate like 20 MHZ used in WiFi and that's why I bought a new workstation with better processor. However, the module still isn't working. The receiver isn't receiving anything at 20 MHZ if it's QAM
