Abstract:
A receiver for use in a communication system, the receiver receiving a received signal, the received signal being a function of an original signal and an original distortion, the receiver comprising:an estimator, the estimator estimating the distortion of the received signal to provide a final estimate of the original distortion, wherein the receiver uses the final estimate of the original distortion to remove the original distortion from the received signal to provide a final estimate of the original signal, whereby the final estimate of the original signal being an estimate of the received signal without the original distortion;a decoder coupled to the estimator, the decoder decoding the received signal, wherein in the process of decoding the received signal the decoder makes a first estimate of the original signal, the decoder providing the first estimate of the original signal to the estimator;wherein the estimator receives the first estimate of the original signal from the decoder and estimates a first estimate of the original distortion based upon the first estimate of the original signal, the estimator providing the first estimate of the original distortion to the decoder, the first estimate of the original distortion contributing to the determination of the final estimate of the original distortion and the final estimate of the original signal.
