SIU'2004 IEEE 12th Signal Processing and Communications Applications, 28-30 April 2004, Cesme, Turkey
LMMSE-variant chip equalizer and MMSE symbol estimator are discussed for the UMTS FDD mode. Since the scrambler is aperiodic in the downlink, LMMSE receiver has to be adapted at chip rate. Modelling the scrambler as stationary random sequence, however, Max-SINR equalizer-correlator structure which might be adapted at symbol rate is obtained from the LMMSE receiver formulation. Linear symbol estimates at the correlator outputs can be refined by MMSE functionalities. Composite performance analysis of the discussed (L)MMSE structures is done and its applicability on estimating the interfering user symbols is discussed.
