摘要： To provide an apparatus for calculation of correlation that can take a correlation even when a frequency error is relatively large. With a 0-th degree correlator (110a) for taking, to output, a correlation between a reference signal and a measurement signal, an n-th degree correlator (110b-n) including an ejwt multiplier (112b-n) for calculating a frequency component addition signal having a frequency component added to the reference signal, and a correlation calculator for taking, to output, a correlation between the frequency component addition signal and the measurement signal, and an adder (120) for adding an output of the 0-th degree correlator (110a) and an output of the n-th degree correlator (110b-n), it is achieved that the output of the 0-th degree correlator (110a) and the output of the n-th degree correlator (110b-n) added at the adder (120) do not have an increased noise/correlation value ratio, even when a frequency error is large. Accordingly, a correlation can be taken even with an increased frequency error.

摘要： A system for bidirectional communication of digital data between a central unit and a remote unit wherein the need for tracking loops in the central unit has been eliminated. The central unit transmitter generates a master carrier and a master clock signal which are used to transmit downstream data to the remote units. The remote units recover the master carrier and master clock and synchronize local oscillators in each remote unit to these master carrier and master clock signals to generate reference carrier and clock signals for use by the remote unit receiver. These reference carrier and clock signals are also used by the remote unit transmitters to transmit upstream data to the central unit. The central unit receiver detects the phase difference between the reference carrier and clock signals from the remote units periodically and adjusts the phase of the master carrier and master clock signals for use by the central unit receiver to receive the upstream data.
摘要翻译：已经消除了用于在中央单元和远程单元之间双向通信数字数据的系统，其中在中央单元中需要跟踪环路。中央单元发射机产生主载波和主时钟信号，用于将下行数据发送到远程单元。远程单元恢复主载波和主时钟，并将每个远程单元中的本地振荡器与这些主载波和主时钟信号同步，以生成参考载波和时钟信号供远程单元接收机使用。这些参考载波和时钟信号也被远程单元发射机用于将上行数据传输到中央单元。中央单元接收机周期性地检测来自远程单元的参考载波和时钟信号之间的相位差，并调整主载波和主时钟信号的相位，供中央单元接收机使用以接收上行数据。
