A new "fractional self-decorrelation" technique is herein proposed to enhance the multipath constructive summation capability and the interference rejection capability of single-user-type DS-CDMA detectors at maximum-SINR blind space-time RAKE receivers to tackle the near-far problem in wireless mobile communications. This technique can significantly decrease the error rate and can remove the near-far problem's error floor at high SNR. Moreover, this "blind" space-time processing receiver architecture needs no prior knowledge nor explicit estimation of (1) the channel's multipath arrival angle or arrival delay or power profile - the fading channel's delay spread may be of arbitrary length, even as long as the symbol duration, (2) the receiver's nominal or actual antenna array manifold, and (3) the other DS-CDMA user's signature spreading codes.
