Near-Far Simulations in CDMA

Started by March 26, 2007
Hi all,
I need to ask anyone who used to do the near-far simulations under Gaussian noise for CDMA system. Based on my brief understanding, in near-far simulation, we need to calculate the performance (BER) of receivers with two interferers, which are one with equal to the desired user and another one with a power which varies from certain dB below the desired up to certain dB above the desired user. Can anyone please give some more explanations since I am still confuse about the concept and on how to come out the near-far simulations.
It is a great help if someone could give me some Matlab codes or algorithms for simulating the near-far simulations for MUD in CDMA.
Thanks and best regards.
