Re: [Discuss-gnuradio] can not connect USRP2 with UHD drivers
Hi Ron, Thank you very much for your help. when i try to do ethtool eth0 Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Link partner advertised pause frame use: No Link partner advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: MII PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x0033 (51) Link detected: yes this is the output i get i have Realtek Semiconductor Co., Ltd.

[Discuss-gnuradio] can not connect USRP2 with UHD drivers
hello, I can't connect to the USRP2 using the latest version of the UHD driver from the git repository. I am using Ubuntu 10.04 and I have followed the instruction at http://www.ruby-forum.com/topic/213259 but still when I connect usrp2 to computer and check the output uhd_find_devices linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.000.001-e2cd276 No UHD Devices Found can anyone help me with this.

[Discuss-gnuradio] problem with the high correlation in noise while receiving in USRP
Hi, I am trying to implement Eigenvalue based sensing method using gnuradio and USRP. and while doing the testing, when we try to receive the noise and do the detection we still get the output as 1 (i.e. the ratio of eigevalues is higher than threshold). This may be due to the high correlation in noise. I tried with removing the antenna and also tried increasing the gain but still the problem is there. I can someone help me with this problem.

Three file are howto_detect_ff.cc, howto_detect_ff.h and howto.i.
