    • An apparatus for monitoring the performance of a distributed system is provided. The distributed system comprises a plurality of cooperating units disposed in a communications network. The apparatus comprises a plurality of diagnostic components wherein each unit of the system comprises at least one of the diagnostic components. Each diagnostic component comprises a sensor, a data reduction module, a transceiver and a data analysis module. The sensors sense unit performance characteristics and represent the characteristics as raw data. The data reduction module receives and processes the raw data produced by the sensors to generate reduced data. The transceiver receives the reduced data from the data reduction module and transmits and receives the reduced data to and from the units using the network. The data analysis module accepts and analyzes the reduced data from the transceiver to produce performance data related to the distributed system.

    • Circuits are provided for transmitted reference spread spectrum systems using a noise-like digital sequence with delayed replica. The circuits produce the digital spreading sequences at extremely high speed, and are capable of providing a great degree of signal spreading. A first embodiment is composed of a low speed section and a high-speed section. This embodiment allows for greater power efficiency without sacrificing sequence speed. In addition, the embodiment also allows shaping of the spectrum of the high-speed digital sequence. Further, this embodiment generates an m-sequence and its near delay by storing decimated pieces of the entire m-sequence over a plurality of end-around circulating shift registers or so-called ring counters. The ring counters can be run at low speed and there is no exclusive-oring operation. A time-delayed transmitted reference spread spectrum transmitter is provided using digital noise generators that are capable of very high speed operation.
    • 使用具有延迟复制品的类噪声数字序列的传输参考扩频系统提供电路。 这些电路以非常高的速度产生数字扩展序列,并且能够提供很大程度的信号扩展。 第一实施例由低速段和高速段组成。 该实施例允许更高的功率效率而不牺牲序列速度。 此外,该实施例还允许对高速数字序列的频谱进行整形。 此外,该实施例通过在多个周边循环移位寄存器或所谓的环形计数器上存储整个m序列的抽取的片段来生成m序列及其近似延迟。 环形计数器可以以低速运行,没有专用操作。 使用能够进行非常高速操作的数字噪声发生器来提供时间延迟的发射参考扩频发射机。
