Re: [Discuss-gnuradio] USRP Basics questions

Hello, Does anyone has some discription about the two programs usrp_fft.py and usrp_oscope.py? I try to search in the archive but didn't find any basic discriptions. For example, I'm using digital-bert benchmark_tx.py to transmit a sequence of 1's, which modulated by BPSK; on the other computer, I

[Discuss-gnuradio] benchmark_rx.py in Digital-bert

Hi, dear all, I was trying to using the benchmark_rx.py in the digital-bert file to receive a BPSK modulated signal from another USRP using benchmark_tx.py, the problem is that even I did not run the benchmark_tx.py, I am still receiving sth with benchmark_rx.py, could anyone explain this to me? o

[Discuss-gnuradio] questions in benchmark_tx

Dear all, I'd like to transmit some data with random 0s and 1s using benchmark_tx.py, can someone tell me that how can I generate such kind of data in benchmark_tx.py for transmission? and what if I want to specify a file to transmit, how to modify the code 'source_file = open(options.from_file, '

[Discuss-gnuradio] generate 0s and 1s

Hi, all, Can anyone tell me which function in Python could I use to generate a fixed length of 0s and 1s? I know in matlab we could just use randsrc(x, y, 0:1), while I've no idea how to implement it in Python. Thanks for ur help! ___ Discuss-gnuradio

Re: [Discuss-gnuradio] how to generate a periodic pulse

Hey, Bruhtesfa, This is Yufeng. I have a more simpler question on Python, do you know which codes can I use to generate a fixed length of random 0 and 1s, and how to modulate them in PSK, do you have any idea about this? Thanks! On Mon, Feb 9, 2009 at 5:11 AM, Bruhtesfa Ebrahim wrote: > Hey a

Re: [Discuss-gnuradio] Gmsk_demod()

Hello, everyone, We've just got two USRPs in our lab and we want to start using them to do some demodulation. I'd like to use one of them to transmit the sum of two (uncoded) signals, useful and interference, with possible relative scaling to simulate different channels. At the receiver side, I w

[Discuss-gnuradio] problem with rx_voice.py

Hi, Recently I was performing the voice transmission between two USRPs. On the transmitter side, with tx_voice.py, it can be seen that data was transmitting, while on receiver side, with rx_voice.py, the data was NOT received. The parameters I set as following: ./tx_voice.py -M 1.0 -I /dev/dsp -f

[Discuss-gnuradio] exploring the GNURadio and USRP with benchmark.py

Hi, dear all, I've just installed GNURadio and Cygwin in two computers, now I'd like to explore them with the experiment using benchmark_rx.py and benchmark_tx.py. I tried to type benchmark_rx.py -f 900M in one computer, but I got 'usb_contral_msg failed' and a warning 'Failed to enable realtime s

Hi, Don, Many thanks for you reply! I've installed gcc, my problem now is that 'make: command not found', do you have any idea on how to solve this? On Tue, Nov 4, 2008 at 8:18 AM, Don Ward <[EMAIL PROTECTED]> wrote: > yufeng wang wrote: > >> I also just st
