Channel quality estimation for link adaptation within interference limited systems
To process received wireless signals received in a receiver, a noise and interference estimate is generated by subtracting the serving cell component from the received OFDM signal, a normalized noise signal is produced by whitening the noise and interference estimate, interference information is detected from the normalized noise signal associated with corresponding reliability information indicating reliability of the interference information, interference cancellation is performed based on the interference information, and a performance indicator indicative of an accuracy of the interference cancellation is adaptively adjusted using the reliability information.
