    • A frequency translating repeater (200) for use in a wireless local area network includes a cancellation unit. Canceller (402) is controlled by control (401) to provide an injection signal for canceling leakage in a receive signal path. Reference coupler (403) provides a reference signal from the transmit signal, injection coupler (404) injects a correction signal, and sample coupler (405) provides a sample for feedback. A processor (510) receives the sample signal through a detector (415). Although the present invention is intended for a frequency translating repeater, it has broad applications in radio transceivers in general. One specific application is with frequency division duplex (FDD) handsets or base stations utilizing CDMA technologies such as W-CDMA and IS-2000 or 1XEV-DV/DO.
    • 用于无线局域网的频率转换中继器(200)包括消除单元。 消除器(402)由控制(401)控制,以提供用于消除接收信号路径中的泄漏的喷射信号。 参考耦合器(403)从发送信号提供参考信号,注入耦合器(404)注入校正信号,并且采样耦合器(405)提供用于反馈的采样。 处理器(510)通过检测器(415)接收采样信号。 虽然本发明旨在用于频率转换中继器,但是它在一般的无线电收发器中具有广泛的应用。 一个具体应用是使用CDMA技术(如W-CDMA和IS-2000或1XEV-DV / DO)的频分双工(FDD)手机或基站。

    • A method and repeater are described for repeating using a time division duplex (TDD) radio protocol. A signal is transmitted from a first station to a second station using a downlink and an uplink. The signal can be detected on the uplink or the downlink. The repeater can synchronize to time intervals associated with the detected signal that are measured during an observation period. The signal can be retransmitted from the second station to the first station if the signal is detected on the uplink and re-transmitted from the first station to the second station if the signal is detected on the downlink. A gain value associated with the downlink can be used to establish a gain value associated with the uplink.
    • 描述了用于重复使用时分双工(TDD)无线电协议的方法和中继器。 使用下行链路和上行链路将信号从第一站发送到第二站。 可以在上行链路或下行链路上检测信号。 中继器可以与在观察期间测量的检测到的信号相关联的时间间隔同步。 如果在下行链路上检测到信号,则如果在上行链路上检测到信号并从第一站重新发送到第二站,则可以将信号从第二站重新发送到第一站。 可以使用与下行链路相关联的增益值来建立与上行链路相关联的增益值。

    • An antenna configuration includes two closely spaced antennas each positioned so as to be orthogonally polarized with respect to the other. The antenna configuration increases antenna isolation and reduces electromagnetic coupling between donor side antenna and repeat side antenna. The antennas include printed dipoles connected to respective transceivers through respective baluns to balance the non-symmetrical portions of the antenna feed paths to reduce unwanted radiation therein. Printed features such as chokes and non-symmetrical and non-parallel structures are preferably included in the ground plane of a multi-layer circuit board to reduce or eliminate circulating ground currents.
    • 天线配置包括两个紧密间隔的天线,每个天线被定位成相对于另一个正交极化。 天线配置增加天线隔离度,减少施主侧天线与重复侧天线之间的电磁耦合。 天线包括通过相应的巴伦连接到相应的收发器的印刷偶极子,以平衡天线馈送路径的非对称部分,以减少其中的不需要的辐射。 诸如扼流圈和非对称和非平行结构的印刷特征优选地包括在多层电路板的接地平面中,以减少或消除循环接地电流。
