APPARATUS AND METHOD FOR INTERFERENCE CANCELLATION IN COMMUNICATION SYSTEMS

摘要

A system that incorporates the subject disclosure may include, for example, determining channel gains for a group of transmitters based on transmitted training symbols; and performing analog time domain cancellation and digital time domain cancellation responsive to a determination that a total interference does not satisfy a threshold range of the analog-to-digital converter, where the total interference is determined based on the channel gains. Other embodiments are disclosed.

主权项

1. A method, comprising:
receiving, by a system including a processor, a signal from each of a group of transmitters, wherein each signal includes training symbols; estimating, by the system, a channel gain for each of the group of transmitters based on the signal from each of the group of transmitters; estimating, by the system, an interference for each of the group of transmitters based on the channel gain; determining, by the system, whether the interference satisfies a threshold range of an analog-to-digital converter of the system for each of the group of transmitters; and performing, by the system, analog time domain cancellation responsive to a determination that the interference does not satisfy the threshold range, wherein the analog time domain cancellation is not performed responsive to a determination that the interference satisfies the threshold range.
