I just cannot see any corporate or even technical advantages in this nor anything that hasn't already been implemented in other forms with more success But, I'll say this was an interesting to say the least demonstration of a possibility.
I think by definition 2:1 is the absolute min requirement for a CDMA system. Without introducing any interference to the channel, I am not sure this demo is very meaningful. Because the advantage of spreading is not shown. Immunity/susceptibility of AWGN also is not proven.. Again, I could be wrong..
BTW, is this company still existing ? If so, could we have the "direct" contact info ?
right ? Because I think I see a pair wireless G modem.
Are you just showing the implemention of FPGA ? Do you employ encryption. If so, does it has provable security ? And what is the strength ? Could you show us your BER vs. Eb/No curve ? What is your data rate ? It is real time right ?

Yes, its is just one link. (We already 2 to 1
multiple access communications demo as shown in the posters.) This is based on the chaos code spectrum spreading (implemented in FPGA).

Correct me if I am wrong.
I don't think you have built the RF front-end
right ? Because I think I see a pair wireless G modem.

Wow. A working demo ?
Would you sync them better ? I couldn't tell.
I think it is just one link right ? Was there any aggressor ? Is it susceptible to microwave oven ? How do you cope with digital
spread & ACI?
