    Abstract: PURPOSE: A downstream transmission apparatus and a method thereof are provided to compensate distortion of a channel on a cable network having channel information. CONSTITUTION: A UL(UpLink) demodulating unit(240) receives a DL channel state of a DL channel from a subscriber device. A DL modulating unit(220) generates a DL stream. A channel processing unit(250) generates a channel value for the DL channel based on the DL channel state. A channel compensating unit(230) compensates the UL channel by the compensated channel value.

    Abstract translation: 目的:提供一种下行传输装置及其方法,以补偿具有信道信息的有线网络上的信道失真。 构成:UL(UpLink)解调单元(240)从用户设备接收DL信道的DL信道状态。 DL调制单元(220)生成DL流。 信道处理单元(250)基于DL信道状态生成DL信道的信道值。 信道补偿单元(230)通过补偿信道值补偿UL信道。
