Abstract :
The multistage (MS) Wiener filter proposed in [J.S. Goldstein et al., Nov. 1998] is extended to meet the best linear unbiased estimator (BLUE) criterion in this research. The MS BLUE filter is shown to share the same structure of the MS minimum-mean squared error (MMSE)/minimum output energy (MOE) filter bank proposed in S. H. Wu et al. [Nov. 2002] for multipath channels modulo a scaling matrix. The limiting performance and the relationship between the output SINRs of MS-BLUE, MS-MMSE and MS-MOE multiuser receivers in a multipath fading channel are derived and linked to the resultant bit rate error (BER). It is shown in our analysis the BERs and SINRs of the MMSE, MOE and BLUE receivers are, respectively in flat Rayleigh fading channels.
