摘要： 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.
摘要翻译：公开了分段CDMA搜索的技术。在一个方面，搜索器包括可选择用于执行多个可分割搜索任务的多个存储元件，每个存储元件可操作用于存储和访问多个搜索任务之一的状态信息。在另一方面，第一搜索任务在进行中中断，存储第一任务的状态信息，执行第二搜索任务，并且使用所存储的状态信息继续第一搜索任务。在另一方面，搜索任务被分割成较小的搜索段，其大小适合于搜索者中的连续可用时间。还提出了本发明的各种其它方面。这些方面具有电路面积和搜索时间效率的优点，从而降低了成本，增加了待机时间，提高了采集速度，提高了信号传输质量，提高了数据吞吐量，降低了功耗，提高了整体系统容量。

摘要： 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.
摘要翻译：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。
