Hi

I want to create a model of MC-CDMA system build usin matlab and then I want to test the performance of variuos types of TCP over this model.

I think that is complete project but I hope to get assistance to do.

Various kinds of TCP ? You mean like TCPv4 and TCPv6 ? Those are the
only official versions of TCP still extent. Some formalized alternatives
to TCP are listed at
http://en.wikipedia.org/wiki/Transmission_Control_Protocol#Alternatives

If you are using your own TCP-*like* protocol then you are strongly
encouraged to use a different IP protocol number (rather than TCP's 6 or
UDP's 17) such as the 253 and 254 that are reserved for experimenting.

Thanks for your answer, But I mean that after I Get efficient MC-CDMA model , I will try to test the performance of ordinary TCP, snoope, freeze, I-TCP, Mobile-TCP, Reno, Vegas, and others.

Are there existing simulation blocks for each of those? TCP itself is
notoriously hard to code _correctly_ and some of the other possibilities
such as SCTP are much more complex. I would go as far as to say that
your only hope of implementing those protocols *correctly* would be by
automatic code (or model) generation from very complete state transition
tables.
