Abstract
In a multi-channel communication system () data () and pilot data () are combined to provide a composite signal comprising discrete data signals (), each having a data portion () and a pilot data portion (). The composite signal is transmitted and a corresponding composite signal received on a communication channel having varying characteristics. An added pilot semi-blind (APSB) channel estimator () and equalizer () apply a converging iterative process to estimate the characteristics of the communication channel and the transmitted data.
