[Discuss-gnuradio] 802.15.4 packet receive using transceiver_OQPSK.grc

hello, i am Jaeho. I am using two USRP X300(one is for transmitter and the other is for receiver), Linux Ubuntu 15.04, gnuradio version 3.7.8, ieee_802_15_4(https://github.com/bastibl/gr-ieee802-15-4). And I find a method to transmit packet by broadcasting with transceiver_OQPSK.grc. As I

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi Daniele, 'MIMO TOP FLOW plots.grc' needed an update. I pushed a new version of this flowgraph which should work now. I had to substitute some blocks. Cheers Johannes On 09.10.2015 10:19, Daniele Disco wrote: > Johannes Demel student.kit.edu>

[Discuss-gnuradio] RTL-SDR source for USRP

Hi all, I have install librtlsdr and now using RTL-SDR source in GNU radio with USRP1 WBX and Basic RX daughter board (Because I saw it support) . I wonder how can I change the subdev devices in this source ? Because when I run flow graph it always choose 'B:0' . Before I used USRP source and

Re: [Discuss-gnuradio] Decoding constellation (0, 1-1) using gnuradio

Hi Abhinav, the problem is that you're not doing BPSK, really. It's an Amplitude shift keying, if you want so. Two things: * you might want to consider what AGC2 does while you're transmitting zeros -- it will increase amplification until noise scales up to signal power. What you're getting after

Re: [Discuss-gnuradio] 802.15.4 packet receive using transceiver_OQPSK.grc

Hi Jaeho, I’m not sure whether I understand you correctly since, actually, the same flow graph can be used to send and receive. Maybe start with a loopback experiment first. When you checkout the project, the output of the phy is fed back to it’s input. This flow graph can be run without any

Re: [Discuss-gnuradio] 802.15.4 packet receive using transceiver_OQPSK.grc

I think my question need to be more detail I have two USRP X300 and two laptop Each USRP connected with laptop through Ethernet cable One USRP (A) is a transmitter and the other USRP (B) is a receiver (A) sends a packet (broadcasting), (B) want to receive these packet from (A) I already saw

For the record: The Mailing list archive seems to be up again, but all mails between the first and the fifth of October seem to be filed under the eighth... I wonder what went wrong on GNU's side... Best regards, Marcus On 10/04/2015 08:24 PM, bob wole wrote: > > > > The ML archive here

Re: [Discuss-gnuradio] 802.15.4 packet receive using transceiver_OQPSK.grc

Hi, you connect the output of the PHY to the USRP source and sink blocks and start it. Then it will actually transmit something. If you do this on two PCs they should receive each others frames. Best, Bastian > On 12 Oct 2015, at 06:48, Jaeho wrote: > > I think my

[Discuss-gnuradio] BER calculation using digital_bert_tx.py and digital_bert_rx.py

Hi everyone, I am trying to calculate BER for bpsk and qpsk using digital_bert_tx.py and digital_bert_rx.py. i want to compare BER of qpsk and bpsk. At same SNR around 20db i am getting constant .16 BER for qpsk and for bpsk it is 1e-12. when i change the SNR using gain of Transmitter and

Re: [Discuss-gnuradio] Correlation Estimator Over the Air

Rich and others, I added the AGC block to RX side and after playing with the parameters for awhile I got a correlation spike! My next step was to confirm that my output equalled my input (byte-wise). In order to accomplish this, I added a Constellation Decoder block after the costas loop and used

Re: [Discuss-gnuradio] 802.15.4 packet receive using transceiver_OQPSK.grc

Thank you for your comment And I have one more question. As I know, instead of IP, 802.15.4 use mac address to communicate between two nodes. So, I think, I must setting mac address for 802.15.4 communication, but I can't find any setting source code from Loopback experiment and

Re: [Discuss-gnuradio] 802.15.4 packet receive using transceiver_OQPSK.grc

I think I should make my question more specific. The address 192.168.10.2 is for USRP A and it is used between A and A's PC(Local Address). And also address 192.168.10.2 is for USRP B and it is used between B and B's PC(Local Address). Both A and B use same address(192.168.10.2), but I think
