Hi,everyone!I really need your help now! I am new to GNURadio and
using GUNRadio 3.2.2 and Ubuntu 10.04 and USRP2 to learn “BBN 802.11b
project.When I ran the,this error occured:
Traceback (most recent call last):
File “”, line 36, in
import Numeric
ImportError: No module named Numeric
And I modified the changing Numeric to numpy(I have seen
an post
saying this solution).
But new error came out:
Traceback (most recent call last):
File “”, line 44, in
class bbn_80211b_mod(gr.hier_block):
AttributeError: ‘module’ object has no attribute ‘hier_block’

So does anyone have the same question? Honestly,I’m so frustrated now!!I
completely don’t know how to deal with this.

And,is the GNURadio version not compatible with the BBN 802.11b Receiver

Hope to see your guy’s anwser quickly!!!
