    • In a remote unit of a wireless communication system, the speed of acquisition, or reacquisition, of a pilot signal by a search engine is increased. PN space is divided into segments and a coarse search of each segment is performed using a set of “fast” search parameters. A set of peak signal strengths, along with their corresponding PN offsets, is saved for each segment of PN space. Following the search of all segments of PN space, the peak signal strengths which were saved during the coarse acquisition are evaluated. Coarse acquisition search results are used by the remote unit to determine fine search window parameters for subsequent searches performed by the remote unit search engine. The fine search parameters concentrate searching efforts on portions of PN space most likely to contain a viable base station pilot signal.
    • 在无线通信系统的远程单元中,增加了搜索引擎的导频信号的获取或重新获取的速度。 PN空间被划分成段,并且使用一组“快速”搜索参数来执行每个段的粗略搜索。 为PN空间的每个段节省一组峰值信号强度及其对应的PN偏移。 在搜索PN空间的所有段之后,评估在粗略采集期间保存的峰值信号强度。 远程单元使用粗略采集搜索结果来确定由远程单元搜索引擎执行的后续搜索的精细搜索窗口参数。 精细搜索参数将搜索努力集中在最有可能包含可行基站导频信号的PN空间部分上。

    • An efficient method and apparatus for implementing a back-end channel matched filter in a receiver is disclosed. A typical channel matched filter embodiment includes a peak detector for establishing processing synchronization from a despread signal, a channel estimator producing a channel impulse response (CIR) estimate from the despread signal based on the synchronization by the peak detector and a back-end symbol combiner coherently combining dominant multipath components of the despread signal by weights based on the CIR estimate based on the synchronization by the peak detector to generate a decision variable. In a digital spread spectrum implementation, the despread signal operated on by the channel matched filter has been previously been correlated with a spreading sequence replica.

    • A method and apparatus for dynamic temperature compensation and pilot stage searcher selection in a mobile unit of a CDMA wireless communication link. Temperature values and measured pilot frequencies are stored in a Temperature Compensation Table and a Temperature Array. The dynamically updated frequency values maintained in the Temperature Compensation Table and Temperature Array are used to determine the searcher stage to be used in pilot signal acquisition. Both the Temperature Compensation Table and the Temperature Array (TA) are updated every 30 seconds after the mobile unit has acquired a pilot signal. The values in the Temperature Array correspond only to values measured during the current phone power on cycle. If the mobile unit loses acquisition with a pilot signal and must reacquire, the acquisition software examines the TA values to determine whether or not the current temperature is saved in the TA. If the current temperature is saved in the TA then a recent frequency estimate exists and the pilot acquisition software uses the frequency estimate and utilizes a fast searcher algorithm. If the current temperature is within a predetermined threshold of the values saved in the TA, the pilot acquisition software calculates a weighted estimate of the frequency based upon the values saved in the TA and values previously saved in the Temperature Compensation Table. The acquisition software then makes a decision of which searcher stage to be used based upon the weighted frequency estimate.
    • 一种用于CDMA无线通信链路的移动单元中的动态温度补偿和导频级搜索器选择的方法和装置。 温度值和测量导频存储在温度补偿表和温度阵列中。 使用温度补偿表和温度阵列中维护的动态更新频率值来确定在导频信号采集中使用的搜索器级。 温度补偿表和温度阵列(TA)都在移动单元获取导频信号后每30秒更新一次。 温度数组中的值仅对应于当前电话通电周期内测量的值。 如果移动单元用导频信号丢失采集并且必须重新获取,则采集软件检查TA值以确定当前温度是否保存在TA中。 如果当前温度保存在TA中,则存在最近的频率估计,并且导频采集软件使用频率估计并利用快速搜索器算法。 如果当前温度在保存在TA中的值的预定阈值之内,则导频采集软件基于保存在TA中的值和先前保存在温度补偿表中的值来计算频率的加权估计。 然后,采集软件基于加权频率估计来确定要使用哪个搜索器级。
