Abstract
A method for equalizing a wireless communication channel includes transmitting a data signal over a primary channel. During transmission of the data signal, a corresponding data signal is sent over a secondary channel. The information received from the secondary channel is compared to the information received from the primary channel and differences between the information received from each of the channels are observed. These differences are used as inputs to an equalizer algorithm that may be used to reduce distortion of the data signal sent over the primary channel.
Claims20
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.

A method, comprising:
- receiving a first data signal from a first communication node over a primary channel at a second communication node;
- receiving a second data signal from the first communication node over a secondary channel at the second communication node, wherein the second data signal includes information corresponding to the first data signal;
- demodulating the first data signal and the second data signal received at the second communication node;
- comparing the first data signal to the second data signal as received at the second communication node;
- compiling distortion data based on the differences between the first data signal and the second data signal;
- transmitting the distortion data from the second communication node to the first communication node over the secondary channel;
- and
- inputting the distortion data into an equalizer algorithm to reduce distortion in future transmissions over the primary channel.
