Re: [Discuss-gnuradio] Any friend working on Hydra from UT austin? How about the performance.

[Alex Zhang]

Thanks Andrew, i will try to manually adjust these parameters to find the optimized performance.

But before that, I really want to know any existing benchmark on the performance over this GNURadio OFDM. 

For example, on what kind of host-pc, what kind data rate have you reached, with how much packet loss rate?

I would assume GNUradio's OFDM is mathematically identical to Hydra,
have you tired finding what settings ( Channel spacing, FFT size,
Number of sub-carriers, Sub-carrier modulation scheme, symbol length,
guard interval, Sub-carrier spacing, and FEC ) hydra uses and setting
GnuRadio to that. It should yield identical throughput.

Alex,

Dreams can come true – just believe.
