Re: [Discuss-gnuradio] laser and infrared

2011-03-31 Thread mrahaim
I'm currently using GNU Radio for an application in Visible Light Communication, which has similarities to IR. Since both are IM/DD, I use the LFTX and LFRX daughter cards with USRP2's and I've been working on implementing some baseband modulation techniques. I was also able to test with so

Re: Re[Discuss-gnuradio] g:Books on GNU RADIO AND USRP IMPLEMENTATION

2011-02-17 Thread mrahaim
I attempted to find a good book on GNURadio when I first started working with it and I came across a book called "Software Defined Radio with GNURadio and USRP" by Cory Clark. The bad news is I haven't found any place where I could purchase it (Seems to be out of print?). I'm curious if any

[Discuss-gnuradio] OFDM on USRP2

2011-01-10 Thread mrahaim
Hi all, Does anyone know of any updated OFDM benchmark code that is modified to be run on a USRP2? I have seen previous posts of this, however the link to the updated code is no longer available. Thanks, Michael Rahaim Graduate Research Assistant Smart Lighting Engineering Research Center

[Discuss-gnuradio] Highest Datarates with GNURadio

2011-01-04 Thread mrahaim
Hi All, I started working with GNURadio a few months ago as a platform for use with a Visual Light Communication front end. I've had some good success with the basic benchmark testing and implementation of a few basic tests with GRC, but I'm curious as to what datarates have been achieved w

[Discuss-gnuradio] USRP Amplifier

2010-11-16 Thread mrahaim
Hi Everyone, Does anyone have a suggestion for an off the shelf low frequency amplifier to use with the USRP? I have a USRP2 with a LFTX board and I run the RF output to a Bias T attached to an LED driver (I'm using the system as a Visual Light Commmunication setup). I noticed that the Ett

[Discuss-gnuradio] GNURadio with VLC - IM/DD Modulation Techniques

2010-10-04 Thread mrahaim
Hi Everyone, I'm writing to ask if anyone is familiar with work being done using the GNURadio project for communication outside the RF spectrum. I've been working with the software and USRP for about a month and I'm using a Visual Light Communication (VLC) front end for the physical link. I

I just started working with gnuradio and I was running into the same problem. After the 'make install', I had to run the following sudo ldconfig /usr/local/lib in order to get my module linked to the library. -Mike Quoting weizhongshan : I am trying to write my own module ,"make" ,"mak
