Re: [Discuss-gnuradio] Is RFX900 simultaneous transmit and receive funtion possible?

Hi all, I used the usrp1 for implementing a UHF gen2 reader(not the entire functionality though). I have used a single board at the same frequency without any problem. RFX900 has 2 antenna ports TX/RX and rx2 so tx and rx antennas can be connected simultaneously. However I found a major problem

[Discuss-gnuradio] fpga verilog question

I am trying to transmit an ASK packet from the usrp fpga(verilog) without using usb data. I cant figure out where should I put the I-q data in verilog. does anyone know what clock(rate) is used to transfer it to ad9862? I observed that the tx_sync signal decides whether data on tx_a[13..0] is

[Discuss-gnuradio] USB latency problem

I tried to use the usrp for implementing rfid protocols, however the USB latency is causing a bottleneck and I cannot generate and send the reply packet before the timeout(I need to send the reply within 80-120 us). upon reading Thomas Schimd's paper(http://nesl.ee.ucla.edu/document/show/242), i

[Discuss-gnuradio] building fpga code in QuartusII

I am trying to modify the fpga verilog code for usrp1. I have installed Quartus-II on windows. does anyone know how to build the code? is there a project file? I need a single Tx and Rx channel(both I-Q). can I modify the verilog code along the lines of inband1rxhb_1tx.rbf ? This would free u
