Abstract
In this letter, a new "fractional self-decorrelation" technique is proposed to enhance the multipath-constructive-summation and 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 reduce the near-far problem's error floor at high SNR. 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 users' signature spreading codes.
