Re: [Discuss-gnuradio] Info regarding full duplex operation of RFX2400

Hi Greg, Thanks. What if I use "two" GNURAdio boards at the same time, one for TX and another for RX. However, they are now placed very close to each other(say <10cm). Do you think this will be a good idea to achieve isolation between TX and RX chains?? Rohit On 3/22/07, Greg Troxel <[EMAIL P

Hi, I have question regarding the full duplex operation of RFX2400 board. Looking at the circuit diagram of the board, I understand that each RFX2400 board has seperate receive AND transmit chain. Hence, if I connect one antenna to "RX" port and another different antenna to "TX/RX" port and use t

Hi, We are working on using GNURadio for using it as RF node capable of 2*2/4*4 MIMO. All the RF nodes are connected to very big FPGA like the one used in "Berkeley Emulation Engine (BEE)" using "Infiniband" Optical Fiber. All the signal processing is implemented in "BEE" hardware. We wanted to r

Hi Eric/Matt,   We are trying to build GNURadio based channel emulator/TX-Rx chain for 802.11b signals but the as you guys know USB is bottleneck right now to process wideband sampled signals. Do you guys see anyway in future that this bottleneck be removed and all the data sampled from wideb
