[Discuss-gnuradio] anyone implement the Raleigh fading model / multi-path?

2008-01-23 Thread George Nychis
Lord Rayleigh called, he wants his fading model in GNU Radio :) In all seriousness, has anyone implemented the Rayleigh fading model in GNU Radio and just not released it? It's kind of a shot in the dark, but from reading the list people seem to do extensive work in GNU Radio and not contribu

Is there any progress on this attempt? I can't find any fading model in python. -- View this message in context: http://gnuradio.4.n7.nabble.com/anyone-implement-the-Raleigh-fading-model-multi-path-tp23782p42327.html Sent from the GnuRadio mailing list archive at Nabble.com. __

There are currently two fading model blocks that are usable in 3.7 both should show up in GRC - or from python you can use: the flat fading model: channels.fading_model( 8, 10.0/samp_rate, False, 4.0, 0 ) where args are {# sinusoids, fDTs, los_component, rician_factor, prng_seed } and a s

Tom, in your email exchange with Richard Clarke on 29 Jan 2008, as shown below, it was mentioned that a multi-path channel model might be integrated into GNU Radio library. I am wondering whether this has happened or not? If not, do you still have code written by Richard's student? If so, woul

There is a standalone, offline HF channel simulator in C for Linux, available through http://www.johanforrer.net/SIMULR/. The code is GPL 2. It might give a head start to anybody developing a gnuradio block. 73 Frank AB2KT On Jan 24, 2008 12:34 AM, George Nychis <[EMAIL PROTECTED]> wrote: > Lord

Hi George, I have had a Summer student doing some work on this (a year ago now). He implemented a GNU Radio module that can do Rayleigh channel simulation. He based it on a particular paper (I'd have to look it up) for the implementation. He verified the statistical performance of his impleme

Hi Richard, This would be great! I have great use for this, and I'm sure many others would too. Did he generate any documentation showing his evaluation of his implementation, and any details of it? (like a final research paper). Could you make this code publicly available to the list so
