Apparatus and method for interference cancellation in communication systems

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.
