Apparatus and method for interference cancellation in communication systems
First Claim
1. A method, comprising:
- determining, by a processing system comprising a processor, an interference based on a group of interference signals received at a receiver from a group of transmitters, wherein the determining the interference is based on channel gains that are estimated for the group of transmitters, and wherein a portion of the interference is self-interference generated from transmitting and receiving at a same time; and
determining, by the processing system, whether or not the interference satisfies a threshold range of an analog-to-digital converter of the receiver for each of the group of transmitters,wherein an analog time domain cancellation is performed responsive to a determination that the interference does not satisfy the threshold range, andwherein a digital time domain cancellation is performed responsive to a determination that the interference satisfies the threshold range.

Abstract
A system that incorporates the subject disclosure may include, for example, determining an interference based on a channel gain for each signal of a group of signals received at a receiver from a group of transmitters. A determination is made of an interference value based on a group of interference signals received at a receiver from a group of transmitters, wherein the interference value is based on channel gains that are estimated for the group of transmitters, and wherein a portion of the interference is self-interference generated from transmitting and receiving at a same time. One of an analog time domain cancellation, a digital time domain cancellation or both, is performed responsive to a determination that the interference value does not satisfy a threshold range of an analog-to-digital converter of the receiver. Other embodiments are disclosed.
