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

[Damindra Bandara]

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 suggest me to write a new block?
2- If the current block can support, is there any documentation I could refer?

Thanks,
Damindra

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 single logical data stream.

But you can of course also write a OFDM Carrier Allocator (compare tx_ofdm.grc)

Best regards,

Marcus

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 channel.

Thank you,

Damindra
