    • A method, an apparatus and a system for eliminating aliasing noise in a multi-carrier modulation system are disclosed. The method includes: acquiring a first power spectrum density template; acquiring information of in-band subcarriers whose aliasing noise is greater than background noise, and acquiring a difference between the aliasing noise and the background noise of the in-band subcarriers; adjusting the first power spectrum density template according to the information of the in-band subcarriers and the corresponding difference to obtain a second power spectrum density template; and sending signals according to the second power spectrum density template. The method, the apparatus, and the system disclosed herein eliminate the aliasing crosstalk noise, improve the performance and stability of in-band services without involving upgrade or modification of the Customer Premises Equipment (CPE), and are easy to implement.

    • A method involving: (i) detecting one of a plurality of possible directional input commands for controlling the position of a cursor in a display; (ii) determining whether the detected directional input should be interpreted as an input under a free-roaming mode or under an attraction mode (iii) if the detected directional input is interpreted as an input under the free-roaming mode then determining an end position at a predetermined magnitude from the current position on a bearing determined by the detected directional input (iv) if the detected directional input is interpreted as an input under the attraction mode then determining the end position as coincident with a selectable item; (v) moving the cursor from the current position to the determined end position in a series of steps; and (vi) setting the end position as the current position.
    • 一种方法,包括:(i)检测多个可能的方向输入命令中的一个以控制显示器中的光标的位置; (ii)确定检测到的方向输入是否应被解释为在自由漫游模式下或在吸引模式下的输入(iii)如果检测到的方向输入被解释为自由漫游模式下的输入,则确定结束位置 如果检测到的方向输入被解释为在吸引模式下的输入,则以与检测到的方向输入(iv)确定的轴承上的当前位置相距预定的大小,然后确定结束位置与可选项目一致; (v)在一系列步骤中将光标从当前位置移动到所确定的结束位置; 和(vi)将结束位置设置为当前位置。
