Re: [Discuss-gnuradio] [USRP-users] FPGA devkit using HSMC/FMC RF board?

2014-02-18 Thread Tomas Daujotas
Hi, Paralella has Z7010 plus 16 core microprocessor and costs 99USD only. Too bad we need to wait to order it. http://www.adapteva.com/parallella-board/ This one is very interesting, but can GNURadio bits run on the Epiphany chip? I will answer a typical engineering answer: it depends.

Good day all. I wanted to let you know that I got the gr-fcdproplus driver working. After doing some digging around and getting nowhere I flushed my Debian system, did a clean install, updated it to the current stable release, carefully downloaded all the Gnuradio requirements, downloaded and

[Discuss-gnuradio] (GSoC) MIMO stuff in GNU Radio

2014-02-18 Thread YiZiRui Zhou
Hi all, I'm Zhou, a graduate student now. I'm pretty interested in MIMO systems, especially Multiuser-MIMO, since it can increase the total throughput of the network significantly. But to the best of my knowledge, there seems no related standard blocks (gr-mimo or something) to achieve this in

Hi Nathan, Thanks for your reply :) I've done little python before, am trying to incorporate a collaborators code into my system and he's used python. I am used to C, where it would copy the pointer. I understand your advice - thanks, I will look at the link. The return value is mimicking
