[Discuss-gnuradio] ofdm occupied tones concept

Hi all, I'm thinking about implementing non-contiguous OFDM with gnuradio. So I read the ofdm codes of gnuradio. And I find the occupied tones concept in gnuradio. Is it designed for non-contiguous OFDM? Or it is for other reasons? -- Thanks, Jianfei BUAA _

[Discuss-gnuradio] Parallel transmission and reception....

Hello, I am using Flex900 daughter board with USRP board. I am using TX/RX port for the transmission and for channel sensing, is it possible to do reception process simultaneously so that i can receive what i am transmittingPlease help me this, and If not then give me a good reason that what a

[Discuss-gnuradio] Swept FFT

Ok. So I followed Josh's advice and fed the output of a triangle source into a variable sink. My problem is getting the variable sink to control the usrp source. The variable sink can be of type: Complex, Float, Int, short, or byte. The usrp source is looking for a variable type Real and so

Re: [Discuss-gnuradio] Swept FFT

The type in variable sink needs to match the type output by the triangle source (probably you want float). Anyway, grc will not validate the flow graph if the types does not match. The variable sink sets a variable in python which will be a python float (not be confused with a float in c/c++ w

RE: [Discuss-gnuradio] reprogram the CPLD of USPR2

Dear Matt, Thanks a lot for your reply. I have Xilinx 10.1 installed (ISE, chipscope...). I also have a Xilinx USB platform cable 2 which is connected to both USRP2 and my PC. So can you help to identify the programming process: 1. I modify boot_cpld.v and implement it with Xilinx 2.

[Discuss-gnuradio] My old gnu radio code ( 2007) does not work now :(

Hi All, I am running gnu radio-3.2.2 now. I haven't used gnuradio in a while (since 2007). I had a old gnuradio code (from a project) that generated a signal repeatedly until I ask it to stop, and the source came from a vector source defined in the program (please see below). I know "flow_graph"

Re: [Discuss-gnuradio] DQPSK Modulation/Demodulation issue

anyone? Surely someone has created a dqpsk trasmitter/receiver that works with a simple vector source as input & vector sink as output. -- View this message in context: http://old.nabble.com/DQPSK-Modulation-Demodulation-issue-tp28288015p28431613.html Sent from the GnuRadio mailing list archi
