    Abstract: 一种扩展频谱接收机包括多个分离多径指。每个分离多径指分解扩展频谱信号。分离多径组合器组合分离多径指的输出。控制电路对分离多径指设置第一位序列的解扩频编码。然后控制电路连续地变化时序偏移量。控制电路响应分离多径组合器的输出,确定它的相对于参考值的时序偏移量,并且根据确定的时序偏移量对分离多径指设置第二位序列的解扩频编码。如果接收机失去信息信号的正确时序跟踪,控制电路连续地变化分离多径指的时序偏移量。

    Abstract: Techniques for cell reacquisition and reselection that increases time spent in low-power mode while effectively monitoring neighbor cells are disclosed. In one aspect, one or more windows around the expected location of the serving cell are searched in the period of time prior to the page indicator. In another aspect, intra-frequency neighbor cells are searched first to determine reselection candidates. Various other aspects are also presented. These aspects have the benefit of increasing time spent in low-power mode, thereby reducing power consumption and increasing standby time.

    Abstract: The present invention concerns a new type of rake receiver, namely, a multimode rake receiver, which may be included within either a mobile station or a base station, and which has dynamic pilot signal searching and multipath reception and combining capability, for CDMA, cdma2000, W-CDMA, or other mobile communication systems. The adaptive, multimode rake receiver includes a network interface, a plurality of adaptive multimode rake fingers, and a multimode processor. Each adaptive multimode rake finger and the multimode processor are responsive to first configuration information (a first mode signal) to configure for a path reception functional mode and are further responsive to second configuration information (a second mode signal) to configure for a searcher functional mode, providing the multimode rake receiver with acquisition, traffic, and idle modes. In the preferred embodiment, the multimode rake receiver is implemented using a new category of integrated circuitry for adaptive or reconfigurable computing, providing a plurality of heterogeneous computational elements coupled to an interconnection network, to form adaptive and reconfigurable multimode rake fingers and a multimode processor, for a plurality of different functional modes, including pilot signal searching and multipath reception and combination.

    Abstract: A wireless time division duplex communication system using code division multiple access has a base station and user equipments. The system communicates using communication bursts. Each communication burst has a unique channelization code and a midamble code. Each midamble code is mapped to a set of at least one channelization code. For each communication burst to be transmitted in a time slot from the base station, the midamble code mapped to that burst's channelization code is determined. Communication bursts are generated and transmitted in the time slot. Each burst has the determined midamble code for its channelization code. The user equipment receives the bursts and determines each received midamble code. The user equipment determines the channelization codes of the transmitted communication bursts based on in part a result of the determining of each received midamble code.
