Re: [Discuss-gnuradio] OFDM implementation for high data rates

[Ron Economos]

There's the DVB-T transmitter and receiver in the Digital Television 
component of GNU Radio. It's capable of 31.6 Mbps in a standard 8 MHz 
bandwidth. (and can be used at higher bandwidths).

I have some OOT modules that allow sending IP packets over DVB. Note 
that these modules only implement the transmit portion and are meant to 
be used with commercial receivers.

One of the drawbacks is that DVB-T is a streaming protocol, so a two-way 
link would require a full-duplex RF system. Also, latency is pretty high 
due to the long frame size used in DVB-T. You can get a much lower 
latency with the DVB-T2 transmitter (which has adjustable frame size), 
but there's no companion DVB-T2 receiver in GNU Radio (you have to use a 
commercial DVB-T2 receiver like the PCTV 292e).
