[Discuss-gnuradio] 2-Rx and 1-Tx

2010-04-09 Thread abbasi9999
Hi After reading: 1. usrp_wfm_rcv2_nogui.py 2. multi_file.py I found a way to solve my problem but its difficult to implement. I want to use one daughter board for only receiving, it has almost the same as sensing signal processing blocks (as in usrp_spectrum_sense, already implemented). As for

Thanks Jason, To make the things simple I have first tried sensing with a single channel (This code is well known and some where available on this forum or GNURadio examples), it is working fine. In this code I simply display the maximum value of each FFT scan. When I have some data source at the

I think that you have the de-interleaving and the mux set up correctly provided you are using a complex source, but there may be other problems with your set up that I'm not aware of with regards to those problems. I think one problem might be your use of a vector sink as a receiver, usually the o

Hello all, After lot of efforts I am able to receive some data one one of the RX channels, but it is too bad. To understand how weak it is, for example, I was actually transmitting a already known data string and then on reception I was comparing it bit-by-bit with the actual packet and in this w

Hallo everyone, I dont get any reply so far, may be I can rephrase my question. Actually I was expecting that any code which is working fine for a single antenna, will only need little changes (Mentioned above in 1st post on this thread) to convert it to multiple antenna. I mean I was expectrin

In addition to my above mentioned question, please also comment on what should be the value of mux (I am setting 0x3210) and what should be the value of fpga_filename, Please again note that I want to use 2 RFX2400 cards with one USRP1, and 2 rx streams will be there each through RX2 antenna of 2

Hello every one, I am using USRP1 + RFX2400. I want to use 2 RFX2400 cards. Overall I will have 2 RX streams and 1 TX stream from this system. Following are main parts of my RX_Path (complete code for RX-Path is also attached, if you want please have a look on that, TX-path is not here). I am un
