Are you sure? Last time I checked, the RPi3 could not perform realtime (quite simple) filtering at 10 MHz. I doubt it can handle the 20 MSPS of the 802.11. On 12/12/2016 09:01 PM, Eric Yates wrote: Hi Paul, Thanks for the quick response. The RPi 3 had enough processing power to receive a me

Dear Marcus, Thank you for your response. My objective is to send multiple streams of data. For example a transmitter to use two different streams to talk to two receivers. I was thinking something similar to Frequency Division Multiplexing, where each stream is represented using a different sub

Dear Damindra, To me, that sounds like a higher-level problem – ie. you can send whatever you want across your OFDM link, and that includes e.g. ethernet or IP packets with different destinations; that would make things more flexible – you wouldn't have to statically assign a set of carriers to a

Dear Marcus, Thank you for your suggestion. However, according to my use case, I cannot do multiple transmissions at a higher layer. I have few questions about the "OFDM Carrier Allocator." 1- Can current "OFDM Carrier Allocator" support multiple streams using multiple channels, or you sugges

Dear Marcus, Thank you very much for being patient with me and answering all my questions. I have one last question. Is there a good reference you could recommend me to read, to understand how the current GNURadio OFDM implementation works? Best regards, Damindra On Tue, Dec 13, 2016 at 6:10 PM,

[Discuss-gnuradio] uhd_images_downloader with RFNoC

On https://kb.ettus.com/RFNoC_Getting_Started_Guides it says "We will be updating the default image occasionally, and you can run uhd_images_downloader again after running git pull and re-installing." 1. What would I be pulling and re-installing (UHD)? If I opt not to configure a github account,
