[Discuss-gnuradio] Ways to improve latency of a low bandwidth stream

2018-04-05 Thread Mario Rossi
Hello list! I'm using named pipes to stream data that I want modulated to gnuradio and I'm receiving modulated samples back using the same named pipes method. I then forward the modulated samples to a SDR via some low latency C implementation I wrote and perform the same operations in reverse a

Hz, how far would I be from decoding DRM radios? I've seen the something for ATSC exists already: how would it work for DVB, analogue TV or DRM? Thanks On 12/7/06, Chris Stankevitz <[EMAIL PROTECTED]> wrote: Mario Rossi wrote: > GNUradio looks very interesting, but I haven't

[Discuss-gnuradio] GNU radio: where to start?

2006-12-06 Thread Mario Rossi
Hi, I've discovered this project yesterday, while looking for Linux driver for a DRM receiver. GNUradio looks very interesting, but I haven't found too much documentation for very beginners (I'm not en engineer, and I've problems understanding many things behind radio and frequencies). This is

FYI, there's a copy of the FX2 technical ref manual here: http://comsec.com/usrp/FX2_TechRefManual.pdf (There may be a later version somewhere else) Thanks > Big question: does it have anything to do with GNUradio? You could integrate this gadget with GNU Radio. Note that it's really just a t

2006-12-05 Thread Mario Rossi
I'm a newbe to GNUradio, which I've found on the Internet searching for documentation about the USB chip Cypress 68013. I'd like to control a DRM receiver (the FDM77 http://www.elad.it/FDM77page.asp) in a Linux environment. This is a software radio which is good to be used as a DRM receiver (cou
