SDMA = Space Devision Multiple Access
This is a new method in Multiple Access like FDMA and CDMA.
In SDMA, each signal seprate in space for example by smart antenna or other method.
I think i can help you couse i prepared a paper
on "SDMA" for the "Student Conference on Electrical Engineering" in Tehran(Iran).
i will soon upload more papers.
you can also search these:
"smart antenna"
"adaptive antenna"
"beamforming"
"scheduling"
"cellular system"
you can download a book about Smart Antenna.(3.32 MB)
it's very usefull.don't miss it.
search this title:"crc.press.smart.antennas.jan.2004.ebook-ddu"
author:Lal Chand Godara
I have many papers.but i received an error while uploading.i'll do my best to upload them again.
thank you so much, i am working on multiuser detection of combined CDMA and SDMA, what about you, pleas send to me some thesis about SDMA
thanks again

I'm working on "Adaptive Antennas"
a usefull book to understand the sellular system is
Simulation and Software Radio for Mobile Communications
by:Hiroshi Harada,Ramjee Prasad
it explains how to simulate a sellular system in MATLAB
it has also somthing good about CDMA.
you can find this book from internet.
it's about 18MB and unfortunately i use a dial up modem and can't
upload it.
i think you would find it in "rapidshare"
