The purpose of adaptive channel equalization is to compensate for signal distortion in a communication channel. Communication systems transmit a signal from one point to another across a communication channel, such as an electrical wire, a fiber-optic cable, or a wireless radio link. During the transmission process, the signal that contains information might become distorted. To compensate for this distortion, you can apply an adaptive filter to the communication channel. The adaptive filter works as an adaptive channel equalizer.
The following figure shows a diagram of an adaptive channel equalization system.
In the previous figure, s(n) is the signal that you transmit through the communication channel, and x(n) is the distorted output signal. To compensate for the signal distortion, the adaptive channel equalization system completes the following two modes:
Refer to the Adaptive Channel Equalization VI in the examples\Adaptive Filters\Applications\Adaptive Channel Equalization directory for an example that uses the LabVIEW Adaptive Filter Toolkit to compensate for signal distortion.
