[Discuss-gnuradio] USRP Output to Spectrum Analyzer

2018-05-08 Thread Yeo Jin Kuang Alvin (IA)
Hi all, Theoretically, in frequency domain, the spectrum for SQUARE wave should be a SINC and for the spectrum of RAMP wave should be decreasing with every odd harmonics. A question that I want to ask is, will I get to see these frequency spectrum in the Spectrum Analyzer after being transmitt

Trying to get the socket PDU blocks to send and receive a stream of data is proving to be a significant challenge. I miss the simplicity and reliability of the TCP server and client blocks - they always "just worked" for me. I don't understand why they were deprecated only to leave us with these bu

I'm not that familiar wit Raspian, but my impression is that it is binary compatible with the original Pi, which has no neon support. The volk code didn't handle this gracefully until recently. That said, The Pi 3 does support neon and better. For the Pi-3, I'd use something built to take advantag

On a new Raspberry Pi 3, running Raspbian, all apt-get package updates loaded, I'm encountering an error compiling gnuradio (branch: master). I made one modification from the default source code, and that is the neonasm patch to fix a different compile error with a missing instruction on the Pi. H

even without any frequency error, why do you expect that exp[j(w t + phi1)] - exp[j(w t + phi2)] is zero? Achilleas ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

You can download Windows GNU Radio binaries here. http://www.gcndevelopment.com/gnuradio/downloads.htm The author of leandvb is doing some DVB-S2 receiver development, but I don't think it's released yet. To make it work on a regular CPU, it doesn't perform any error correction (no LDPC or BCH

Hi all! My name is Maria and I am a new GNU radio user so I still need to learn quite a lot about it. I am writing this email as I need to emulate a DVB-S2 platform on a Windows machine so I wanted to ask if the DVB-S2 implementation already available in GNU can work as well for Windows. If s
