Hi,

I have already seen this kind of error. Looks like different hardware
architectures produce different results because of computational
accuracy. What does "cat /etc/lsb-release" tell you (Linux version), is
it a 32bit or 64bit installation?

The inaccuracy only seems to affect the IMT-Advanced channel models. If
you don't plan to use them, there is no problem at all. If you depend on
the IMT-Advanced channel models please tell me and I provide some
reference results from the WiMAX IMTA tests to check how far your system
is off.

Greats,

Mac
