Hi.
I was checking the OFDMA project in CGRAN but it is outdated.
However, I am struggling to understand how to define the carriers to use.
The author keeps using the ofdm_mod.reset_carrier_map() method but that
method doesn't exist in the new version.
Using the current GNU Radio version, which
HI Guys,
Have any one ever managed to compile and run the 802.11b receiver verilog
cods from SPAN Lab?
http://span.ece.utah.edu/pmwiki/pmwiki.php?n=Main.80211bReceiver
I found that the BIN version works well (with the default FPGA
configuration image files "usrp_std_d2.rbf").
However, the new FPGA
Ah that makes sense!
Thanks guys!

I'm doing a bunch of testing on the USRP N210 with the XCVR2450.
In particular i'm looking at areas where there is odd behaviour at extremes
etc and at trying to put it in context.
One thing i've started to notice is that as I step up the uhd gain the
readings I get on the spectrum analyser do not

Are you transmitting out of your J1 port? 30dB sounds like cross talk
on a non-transmitting port.

Hi,
I was trying to implement a TDD system using UHD time stamp feature. I
used the UHD API
directly (not gr_uhd) to test it first. The transmit path sends bursts
periodically, and the receive path
captures all the time. For comparison, I have also recorded the signal from
another USRP N200

Vincenzo -
The specs for the B100 ref signal are the same as the E100, not the USRP2.
It can take a signal from 0 to 15 dBm.
Thanks for pointing out this missing bit of documentation. We will add it
immediately.
Cheers,
Ben

Hello,
I am unsure of how to set the CONSTELLATION OBJECT parameter in the GRC
block. I am using GNU Radio 3.6.1. I would greatly appreciate any help.
Thank you.

Hi all,
As far as I know the maximum sampling rate for USRP N210 is 25M sps. To
receive signal with high frequency, such as 300 MHz to 2.2 GH, the RF front
end converts the RF into IF, so the ADC can sample the IF signal. My
question is what the IF value is for daughter-board WBX? Where can I
