    • A digital communications receiver includes an input configured to receive, via a communications channel, a received first signal representing a sequence of symbols, each symbol being encoded to be representative of a plurality of data bits. A processor adjusts a magnitude and filters the received signal. An equalizer applies a cyclic prefix restoration to the adjusted and filtered signal, producing a second signal, converts the second signal from time domain to frequency domain to produce a frequency domain signal, and determines a first quantity of values representing a first portion of the symbols by evaluating a relationship of channel values representing characteristics of the communications channel and a second quantity of values representing a portion of the frequency domain signal, the first quantity being smaller than the second quantity.
    • 数字通信接收机包括被配置为经由通信信道接收表示符号序列的接收的第一信号的输入,每个符号被编码为表示多个数据比特。 处理器调整幅度并对接收到的信号进行滤波。 均衡器对经调整和滤波的信号应用循环前缀恢复,产生第二信号,将第二信号从时域转换到频域以产生频域信号,并且确定表示符号的第一部分的第一数量的值 通过评估表示通信信道的特性的信道值的关系和表示频域信号的一部分的第二数量的值,第一数量小于第二数量。

    • The present invention discloses a fiber amplifier, a fabricating method thereof, and a fiber communication system. The fiber amplifier includes at least a pump laser, at least a gain medium and at least an integrated optical component. The integrated optical component includes multiple optical input/output ports, and the optical input/output ports are connected to the pump laser or gain medium directly or indirectly. The present invention may better address problems of unstable performance and difficulty in reducing the size of components in the prior art where fiber amplifiers are formed by a number of discrete components with many fiber fusion splices. In addition, the present invention may reduce the production complexity and costs of fiber amplifiers, and improve the productivity of fiber amplifiers.
