[Discuss-gnuradio] Firmwareimage Raw Ethernet, No WBX or XCVR MD5

Hi, i have a problem while updating the Firmware and FPGA Image on my USRP2. http://code.ettus.com/redmine/ettus/projects/public/wiki/U2binaries The MD5 check always results a different MD5sum. -> 1ed856757093abe0b58dacdd1b15faf1 *txrx_raw_eth_20100608.bin 3 downloads on different Computers an

[Discuss-gnuradio] ofdm_mod / FTW ofdm: Problem sending a sequence of frames

Hi, im working on a projekt using the Cgran Project FTW IEEE802.11 OFDM frame encoder. https://www.cgran.org/wiki/ftw80211ofdmtx https://www.cgran.org/wiki/ftw80211ofdmtx I use Ubuntu 10.04, Gnuradio 3.2.2 and a USRP2 with 2450 tranciever I have modified the "get_info" function in the ofdm_

[Discuss-gnuradio] FTW 802.11 ofdm encoder, sending multiple packages

Hello @All, i’m working on a project using the FTW 802.11 ofdm encoder Project from Cgran on Ubutntu 10.04 and Gnuradio3.2.2, Python 2.6 , USRP2 RFx2400. Transmitting single Frames works fine. I want to send multiple packages, so i modified the send_pkt function in the ftw.ofdm.py file and call

[Discuss-gnuradio] Problem with output of inverse FFT

Hi @all, on my long way to send multiple 802.11g frames i found another problem… During the process the data is converted from frequency domain to time domain by inverse fft. The fft length is 64, and the input is the OFDM symbol with carrier tones (vector of 64 * gr_complex) The frame consi

Re: [Discuss-gnuradio] Problem with output of inverse FFT

and created again to modulate another OFDM frame, the wrong pilot tones are insert to this frame. After defining "offset" and "i" in the header file (private class elements), the second frame has the same pilot tones. maybe it is possibel to change this in the SVN repository. H
