 技術摘要： |
一種通訊系統包括傳送器和接收器。傳送器包括前饋等化器及等化控制單元。前饋等化器接收數位信號，根據補償係數對數位信號等化調變得到第一已調變數位信號，並透過通道傳送該第一已調變數位信號，其中該前饋等化器更依據一控制信號來調整該補償係數。等化控制單元耦接該前饋等化器，根據通道之損耗狀況產生控制信號，並傳送控制信號至前饋等化器。透過該通道連接該傳送器，該接收器從該通道接收一第二已調變數位信號，並根據一閥值將該第二已調變數位信號解調得到一已解調數位信號，其中該第二已調變數位信號為該第一已調變數位信號經過該通道改變而得到之一雙二位元數位信號。
A communication system is provided. The communication system comprises a transmitter and a receiver. The transmitter comprises a feed forward equalizer (FFE) and a equalizer control unit. The FFE receives a digital signal and modulates the digital signal into a first modulated signal according to a compensating coefficient and transmits the first modulated signal through a channel, wherein the FFE adjusts the compensating coefficient according to a control signal. The equalizer control unit is connected to the FFE, generates a control signal by a loss condition of the channel and transmits the control signal to the FFE. The receiver receives a second modulated signal from the channel and demodulates the second modulated signal into a demodulated digital signal according to a threshold value, wherein the second modulated signal is a duobinary signal transferred from the first modulated signal after transmitted through the channel.
