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: 接收机被配置为用于消除在通过频率选择性通信信道传播的编码的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以及混合决策符号估计。 接收机实施例可以用软件或编程硬件明确地实现，或者隐式地在Rake内（即在手指级）或在Rake外（即在用户或子信道符号级）在标准的基于Rake的硬件中实现。
