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 group of signals from a group of transmitters, wherein each of the group of signals includes training symbols according to an orthogonal frequency-division multiplexing protocol; determining, by the system, a channel gain for each of the group of signals; determining, by the system, a total interference based on the channel gain; determining, by the system, whether the total interference satisfies a threshold range of an analog-to-digital converter of the system; performing, by the system, digital time domain cancellation without performing analog time domain cancellation responsive to a determination that the total interference satisfies the threshold range; and performing, by the system, the analog time domain cancellation and the digital time domain cancellation responsive to a determination that the total interference does not satisfy the threshold range.
