Noise Canceling in Equalized Signals

摘要

A receiver ( 20 ) that is suitable to receive at least two, simultaneously transmitted signals uses a linear equalizer ( 18 ) for equalizing the received signals. Additionally such receiver has a signal quality estimator ( 36 ) to determine which of the equalized signals has the best signal to noise ratio. A noise estimator (31) derives a correlated noise signal (n₁, n₂) from equalized signal having the best signal to noise ratio. This correlated noise signal (n₁,n₂)is used to cancel the correlated noise with another of the equalized signals, so as to improve the signal to noise ratio of that signal.
