Abstract: An intermediate symbol buffer (ISB) configuration and method is provided such that the ISB memory comprises 15 portions, one for each HSDPA spreading code. Symbols associated with a spreading code are written to the memory portion associated with the same spreading code. When a covariance calculation is performed to obtain a more accurate channel estimate, only the symbols associated with spreading codes determined to be needed for the covariance calculation are written to the ISB by a buffer block and red from the ISB by a correlation core. The symbols associated with spreading codes that are not necessary for a covariance calculation may be masked from being written or read from the ISB. In some embodiments each memory portion is an individual memory block. In other embodiments a plurality of memory blocks may contain a plurality of memory portions, one memory partition designated, at least temporarily, or each spreading code.

Abstract translation: 提供中间符号缓冲器（ISB）配置和方法，使得ISB存储器包括15个部分，每个HSDPA扩展码一个。 与扩展码相关联的符号被写入与相同扩展码相关联的存储器部分。 当执行协方差计算以获得更准确的信道估计时，只有与确定为协方差计算所需的扩展码相关联的符号才被缓冲块写入ISB，并通过相关核心从ISB写入红色。 与协方差计算所不需要的扩展码相关联的符号可以被掩蔽从ISB的写入或读取。 在一些实施例中，每个存储器部分是单个存储器块。 在其他实施例中，多个存储器块可以包含多个存储器部分，至少临时地为每个扩展码指定一个存储器分区。
