Abstract :
A modified MMSE receiver for multicarrier DS-CDMA operating in fading, multipath radio channels is presented. This structure is computationally efficient when the channel is rapidly time-varying. Subspace concepts are applied in a proposed blind implementation and simulations show that the new receiver can produce enhanced performance.
