Crosstalk profile detection for use in multiuser detection

Accurate identification of crosstalk interferers can increase throughput by proper loading or multiuser detection. In some systems, such as cable based delivery systems, crosstalk channel characteristics are finite and static. Furthermore, the type of service on each line does not change. The combination of the type of service and the channel characteristic is known as a crosstalk profile. Specific methods are introduced that allow for the detection of a crosstalk profile and further minimize the probability of error in selecting from the set of possible crosstalk interference scenarios.
