摘要： A composite code is made for example by exclusive-OR'ing each real element of a first constituent code A with each element of a second constituent code B to obtain a basic composite code. To suppress autocorrelation, differing numbers of doping code elements are inserted between code segments made from combining each element of code A with an element of code B. A matched filter first stage removes from its input the A code and any doping code added to it, summing the elements of code A. A matched filter second stage removes from its input the B code and any doping code added at the second level. The summed elements of code B are the input to the first stage. Optionally, the summed elements of the doping code at any level may be delayed and summed with the elements of the A code in the first stage.
摘要翻译：例如，通过将第一组成代码A的每个实际元素与第二组成代码B的每个元素进行异或运算以获得基本复合代码来进行复合代码。为了抑制自相关，在将代码A的每个元素与代码B的元素组合而形成的代码段之间插入不同数量的掺杂代码元素。匹配滤波器第一级从其输入中去除A代码和添加到其中的任何掺杂代码，对代码A的元素求和。匹配滤波器第二级从其输入中移除B代码和在第二级添加的任何掺杂代码。代码B的总和元素是第一阶段的输入。可选地，任何级别的掺杂代码的总和元素可以被延迟并与第一级中的A代码的元素相加。

摘要： A correlator despreads a P/N long code constructed from two or more constituent codes A, B, C having N, M and L elements respectively. In a third stage, L filter taps decorrelate elements of the third constituent code from the input received signal, leaving elements of code AB. The outputs of the third stage delay line are summed and input into a second stage delay line having M filter taps to decorrelate the elements of the second constituent code from the input to the second stage, leaving elements of code A. The outputs of the second stage delay line are summed and input to a first stage delay line having N filter taps. The output of the first stage delay line is summed and input into a shift register. An energy peak in the shift register indicates the phase of the P/N elements in the register is proper.
摘要翻译：相关器分别从具有N，M和L个元素的两个或更多个组成码A，B，C构成的P / N长码解扩。在第三阶段，L滤波器从输入接收信号抽头去除关联第三组成码的元素，留下代码AB的元素。将第三级延迟线的输出相加并输入具有M个滤波器抽头的第二级延迟线，以将第二组成码的元素从输入到第二级去相关，留下代码A的元素。第二级延迟线的输出相位延迟线被相加并输入到具有N个滤波器抽头的第一级延迟线。将第一级延迟线的输出相加并输入到移位寄存器。移位寄存器中的能量峰值表示寄存器中P / N元件的相位是否正确。

摘要： A method and system which detects failures in communication between a base unit and an extension unit in a wireless communication system and which resets the system upon detecting such failures is described. A wireless communication system in this invention can use an RF over the air communication channel or an AC power line communication channel. In this method and system failures in the extension unit are detected and the base unit is reset, thereby permitting further use of the telephone communication link. A variety of embodiments are disclosed, including: transmitting a low frequency signal from the extension unit; transmitting a high frequency signal from the extension unit; periodically transmitting a status command signal from the extension unit; and detecting the signal strength of the transmitted signal from the extension unit in the base unit.
