Abstract
This paper describes the unique performance evaluation results of a Gigabit Digital
Subscriber Line modem that provides Multi-user-interference-free communication, by incorporating
Super Orthogonal Complete Complementary spreading into the existing xDSL modem architecture.
The GDSL modem was tested under practical crosstalk conditions, using the Network Interface, Power,
and Protection (NIPP) Committee MIMO Crosstalk Model. It was found that the GDSL modem
provides acceptable bit error rate performance for a fully loaded system, even for very short twisted
pairs. A unique observation from these performance evaluation tests is than the non-linear behaviour of
NEXT and FEXT creates an orthogonality distortion effect on the correlation properties of the SOCC
code family.
