WARP Project Forums - Wireless Open-Access Research Platform

Hi,
I want to transmit/receive  802.11 n signal (33.75 MHz active sub-carriers) using Warplab 7.4  and V3 kit.
Is the right Low Pass Filter Setting can be :
tx_lpf_corn_freq= [3] # enabling 48 MHz bandwidths or it should be [2] or it does not matter [2]or [3]?
rx_lpf_corn_freq= [3]# enabling 36 MHz bandwidths.
CHAN=[11] # Is it ok to handle this bandwidth

I am doing sum measurements but the results are not as I am expecting, so just I want to make sure this setting is not causing the problem. Can you please tell me is this setting OK or I am missing something? Thank you
