Method and System for Improved Interference Cancellation by Path Selection
First Claim
1. A method for improving performance of interference cancellation in a radio communication system, comprising steps of:
- estimating power of an interfering signal contained in a received signal;
estimating power of an additive estimate error signal added to the interfering signal; and
canceling the interfering signal from the received signal if the estimated power of the additive estimate error signal is lower than the estimated power of the interfering signal.

Abstract
The present invention discloses method and system for improving performance of interference cancellation in a radio communication system. The method comprises: estimating power of an interfering signal contained in a received signal; estimating power of an additive estimate error signal added to the interfering signal; and canceling the interfering signal from the received signal if the estimated power of the additive estimate error signal is lower than the estimated power of the interfering signal. A cellular mobile terminal and a cellular base station comprising the system are also disclosed.
