    Abstract: Techniques for segmented CDMA searching are disclosed. In one aspect, a searcher comprises a plurality of storage elements selectable for performing a plurality of segmentable search tasks, each storage element operable for storage of and access to state information for one of the plurality of search tasks. In another aspect, a first search task is interrupted in progress, the state information for the first task is stored, a second search task is performed, and the first search task is continued using the stored state information. In yet another aspect, a search task is segmented into smaller search segments, sized to fit within contiguous available time in the searcher. Various other aspects of the invention are also presented. These aspects have the benefit of circuit area and search-time efficiency which translate into reduced costs, increased standby time, increased acquisition speed, higher quality signal transmission, increased data throughput, decreased power, and improved overall system capacity.

    Abstract: Techniques for tracking closely spaced multipath and preventing finger merge without monitoring relative positions between each of a plurality of fingers are disclosed. In one aspect, motion limits are determined for each finger. Time-tracking commands that would move the position of a finger outside its respective motion limits are suppressed. In another aspect, motion limits are updated dynamically, the motion limits of each finger determined in accordance with the motion limits of fingers adjacent to it. Various other aspects are also presented. These aspects have the benefit of preventing finger merge, which allows the allocation of multiple fingers to closely spaced multipath, thus increasing performance and system capacity, and mitigating misallocation of system resources.

    Abstract translation: 公开了用于跟踪紧密间隔的多路径并防止手指合并而不监视多个手指之间的相对位置的技术。 在一个方面，为每个手指确定运动限制。 可以抑制将手指位置移动超过其各自运动极限的时间跟踪命令。 在另一方面，运动限制被动态地更新，每个手指的运动限制根据与其相邻的手指的运动限制确定。 还提出了各种其他方面。 这些方面具有防止手指合并的优点，这允许将多个指状物分配到紧密间隔的多路径，从而提高性能和系统容量，并减轻系统资源的未分配。
