Abstract :
A high-capacity, low-complexity, and robust system design for a successive. interference cancellation (SIC) system is analyzed. Multicarrier CDMA (MC-CDMA) is used to suppress multipath and to overcome the multipath channel estimation problem in SIC systems. An optimal power control algorithm for MC-CDMA with SIC is derived, allowing analytical BER expressions to be found. It is shown that with coding, the capacity of the proposed system approaches the AWGN capacity for SIC even in a fading multipath channel with channel estimation error.
