Abstract :
The desired performance of a wireless system depends on the interaction of the number of users carried by the system, hence, influencing the choice of the multiple access scheme (e.g., FDMA vs. TDMA vs. CDMA). This choice has a major impact on the selection of the power control techniques and on the physical layout of the entire system. It is the intention of this paper to provide a fast converging semi-analytical evaluation of the Bit Error Rate (BER) performance of A/DS-CDMA transmission schemes, incorporating a Wiener filter to countermeasure the effects of the near-far effect present in future wireless communication systems.
