Hallo,
Thanks a lot for your response. Yes, I should have written as OFDMA.
Bythen, I am interested to know how the SNR vs BER of a link varies for
Multiuser interference when it is in the system level. (Simulator
functionality point of view)
Cheers,
Patrick

It sounds like you're talking about OFDMA, and if you are, then
misregistration (in time or frequency or both) of subcarriers from
different users does degrade performance. How much so depends a lot
on the system and is usually determined in simulation.

Hallo,
In an OFDM systems, if the users are not orthogonal, how does the
multiuser interference affects the mapping of SNR to BER (BLER).I do have
only a vague idea about this. Could anyone help me in the right path/ any
literatures.
Thanks a lot in advance
