    • A subscriber unit of a time division multiple access (TDMA) radiotelephone system is, from a power consumption standpoint, reconfigured in each time slot of a TDMA frame to a power consumption tessellation in which subscriber unit circuit components not needed for communication signal processing in that time slot are powered down, and other components are powered up. Some circuit components are powered down by switching their power supply circuits. In order to minimize the extent of circuitry that must be provided to distribute power consumption control signals, other techniques (which utilize circuitry provided for other purposes), such as clock frequency control or power down commands, also are utilized to modify controlled circuit component power consumption without actually controlling power supply circuits. Loop connection length between the subscriber unit and the subscriber s telephone set, or other terminal equipment, is limited to a length which is much less than the length of a radio link on which the subscriber unit operates. Programmable ring frequency logic controls the frequency of a ringing signal generator, and a high frequency ring control signal is switched on and off in the cadence of ringing operation. Also an expansion header is provided to enable serving plural subscriber loop circuits with the same radio equipment for reducing per line power consumption.
    • 从功耗角度考虑,时分多址(TDMA)无线电话系统的用户单元在TDMA帧的每个时隙中重新配置为功耗曲面细分,其中用户单元电路部件不需要进行通信信号处理 时隙断电,其他组件上电。 一些电路元件通过切换其电源电路而断电。 为了最小化必须提供来分配功率消耗控制信号的电路的程度,也利用其他技术(利用为其他目的提供的电路)的诸如时钟频率控制或功率下降命令等来修改受控电路组件功率 而无需实际控制电源电路。 用户单元与用户单元和其它终端设备之间的环路连接长度被限制在一个长度上,该长度远小于用户单元在其上操作的无线电链路的长度。 可编程振铃频率逻辑控制振铃信号发生器的频率,并且高频振铃控制信号在振铃操作的节奏中被打开和关闭。 还提供了一个扩展头,以便能够用同一无线电设备为多个用户环路提供服务,以减少每线功耗。

    • The present invention relates to a base station for receiving a transmitted signal which includes at least one short code which is periodically updated; the base station comprising:

      a despreader for receiving and despreading the transmitted signal to output a despread signal;
      a background noise estimator for obtaining a background noise estimation using the periodically updated short code; and
      a decision unit, which receives the despread signal and the background noise estimate, calculates a value representing the likelihood that a short code has been detected and compares the value with a predetermined threshold; whereby the decision unit confirms the detection of the short code if the value exceeds the predetermined threshold.
