Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 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 interfere…
