Bernard,

I do not know if you are familiar with the patent dates. Our patent is earlier than the first DMT patent. Our solution for the peak to average problem is the one adopted in the IEEE802.11a (I remind everyone that Wi-LAN did not develop the standard and only had one submission to it relating to the forward error correction).

Also, I am not certain that DMT had any intentions of being wideband. We gave a number of definitions of wideband in our patent. These definitions include: 1. if bandwidth occupied is wide enough that the propagation channel is frequency selective meaning different subchannels are subjected to different channel characteristics, or 2. if the subchannels are far enough apart from each other that an implementation can be made without discrete (rf hardware) carrier recovery.

As you must know, I cannot carry this debate much further since, ultimately, this is what courts are for.
