    Abstract: In one example embodiment, a method includes determining a first set of first lines and a second set of second lines in a system, obtaining input signals to be transmitted over the first set of first lines and the second set of second lines, determining a vectoring matrix, processing, within the first set, the incoming signals for the first lines in parallel based on the vectoring matrix, processing, within the second set, the input signals for the second lines in parallel based on the vectoring matrix and processing the first set and the second set sequentially based on the vectoring matrix, the processing the second set being based on at least a portion of the processing the incoming signals for the first lines.

    Abstract: In one embodiment, the method includes determining, at an access node, a precoder matrix for precoding transmission from the access node to a plurality of downstream devices over a plurality of lines. The plurality of lines include high power lines and low power lines. The high power lines are in active communication and transmit more symbols per frame than the low power lines. The method further includes precoding a signal vector using the precoder matrix regardless of the symbols the signal vector is sending over the low power lines. Here, the determining determines the precoder matrix such that the precoding does not mitigate the cross-talk effect the high power lines have on the low power lines. The method also includes transmitting over the plurality of lines based on the precoded signal vector.

    Abstract translation: 在一个实施例中,该方法包括在接入节点处确定预编码器矩阵,用于预编码从多个线路从接入节点到多个下游设备的传输。 多条线路包括高电力线路和低电力线路。 高功率线路处于主动通信中,并且每帧传送比低功率线路更多的符号。 该方法还包括使用预编码器矩阵预编码信号向量,而不管信号向量通过低功率线发送的符号。 这里,确定确定预编码器矩阵,使得预编码不会减轻高功率线对低功率线路的串扰效应。 该方法还包括基于预编码的信号向量在多条线上进行发送。
