For a given decision order, MMSE successive interference cancellation (MMSE-SIC) can simultaneously maximize SIR's of all users. To further increase its efficiency, a power control (PC) algorithm, under equal BER criterion, is proposed in this letter for uplink MC-CDMA. In frequency-selective Rayleigh fading channels, the MMSE-SIC integrated with the equal BER PC suppresses multiple access interference effectively, resulting in a performance very close to the single user bound (SUB).
