摘要

研究了直接顺序码分多址(DS-CDMA)系统中的盲多址干扰(MAI)和码间干扰(ISI)抑制问题。为了利用多径信道固有的多样性，我们引入了一种分两步进行的盲RAKE多用户接收机。首先，使用一组适当的线性约束最大似然线性(LCMLL)接收器从每个传播路径获得期望用户传输符号的软估计。然后，将这些估计充分组合以提高信噪比(SINR)。

A novel blind diversity combining receiver for CDMA systems

This paper addresses the problem of blind multiple access interference (MAI) and intersymbol interference (ISI) suppression in direct sequence code division multiple access (DS-CDMA) systems. In order to take advantage of the diversity inherent to multipath channels, we introduce a blind RAKE multiuser receiver that proceeds in two steps. First, soft estimates of the desired user transmitted symbols are obtained from each propagation path using a bank of appropriate linearly constrained maximum likelihood linear (LCMLL) receivers. Afterwards, these estimates are adequately combined to enhance the signal to interference and noise ratio (SINR).
