    摘要: 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.

    摘要: 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.
