Abstract: A receiver is configured for canceling intra-cell and inter-cell interference in coded, multiple-access, spread-spectrum transmissions that propagate through frequency^selective, communication channels. The receiver employs iterative symbol-estimate weighting, subtractive cancellation with a stabilizing step-size, and mixed-decision symbol estimates. Receiver embodiments may be implemented explicitly in software or programmed hardware, or implicitly in standard Rake-based hardware either within the Rake (i.e., at the finger level) or outside the Rake (i.e., at the user or subchannel symbol level).

Abstract translation: 接收机被配置为消除通过频率选择性通信信道传播的编码，多址，扩频传输中的小区内和小区间干扰。 接收机采用迭代符号估计加权，具有稳定步长的减法消除和混合判决符号估计。 接收器实施例可以在软件或编程硬件中明确实现，或者隐含地在Rake（即，在手指级）处或Rake外部（即在用户或子信道符号级别）处于标准Rake的硬件中。
