1. A system, comprising:
a first communication node configured to transmit a first data signal over a primary channel and a second data signal over a secondary channel, wherein the second data signal includes information corresponding to the first data signal;
a secondary communication node configured to receive the first and second data signals transmitted from the first communication node;
wherein the secondary communication node is configured to compile distortion data by comparing the received first data signal to the received second data signal; and
wherein the distortion data is sent from the second communication node to the first communication node using the secondary channel.
