Re: [Discuss-gnuradio] Replacement for packet encoder/decoder

Hi Damindra! Ha, you're more than welcome! Sorry, I don't have a good reference more than the example tx_ofdm.grc and rx_ofdm.grc, the doxygen documentation to the blocks used therein and their source code, if you care for implementation details. Best regards, Marcus On 14.12.2016 01:09,

Re: [Discuss-gnuradio] Replacement for packet encoder/decoder

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

Re: [Discuss-gnuradio] Replacement for packet encoder/decoder

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

Re: [Discuss-gnuradio] Replacement for packet encoder/decoder

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

Re: [Discuss-gnuradio] Replacement for packet encoder/decoder

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

Re: [Discuss-gnuradio] Replacement for packet encoder/decoder

We'll have to discuss what you mean with "channels" – do you mean separate OFDM *signals*, or do you mean multiple *streams of data*? Best regards, Marcus On 12/12/2016 08:09 PM, Damindra Bandara wrote: > Dear Tom and Marcus, > > Thank you very much for pointing me to OFDM example. I was able

Re: [Discuss-gnuradio] Replacement for packet encoder/decoder

Dear Tom and Marcus, Thank you very much for pointing me to OFDM example. I was able to use that example and accurately transmit and receive files using X310 USRPS. I have a follow-up question. How can I modify these flow graphs to transmit multiple channels(that is transmitter talking to

Re: [Discuss-gnuradio] Replacement for packet encoder/decoder

Dear Marcus, Sorry, but for some reason I did not received this message from Tom and also missed it in the GNURadio thread. I will check it and see whether it will solve my problem. Thanks, Damindra On Tue, Dec 6, 2016 at 6:08 PM, Marcus Müller wrote: > Hi Damindra,

[Discuss-gnuradio] Replacement for packet encoder/decoder

Hi, I have noticed that packet encoder and decoder blocks are deprecated in latest GNURadio version. I appreciate if someone could let me know what are the replacement blocks for them. Thank you, Damindra -- Damindra Savithri Bandara, Ph.D. in Information Technology (Candidate) George Mason
