Dear all,
To reduce the influence of CFO, we need to run our system with large bandwidth (like 802.11 at 20MHz). However, once we set the transmitting bandwidth larger than 2MHz, the receiver's program will block there and show "over-run" message later on (a screen of "O"s). For small bandwidth (<2MHz), the receiver runs pretty well.
Do you have similar experience? How can I make the OFDM receiver work with 20MHz bandwidth?
We use USRP N210. And the configuration of our PC is
Ubuntu release 10.10(maverick) kernel 2.6.35-22-generic GNOME 2.32.0
Memory: 15.7GiB
Processor 0~7: Intel(R) Xeon(R) CPU E5620 @ 2.40GHz
UHD version: UHD_003.004.000-c50bb91 image version 8
gnuradio version: 3.4.x
Sincerely,
