Abstract:

The present invention provides a receiver for underwater acoustic telemetry that combines a decision feedback adaptive-equalizer structure with a turbo-equalizer structure. The turbo-equalizer structure is of significantly reduced complexity because the decision feedback adaptive-equalizer structure is operable to pre-process a plurality of data channels to provide a single symbol data output stream for application to the input of the turbo equalizer. The turbo-equalizer structure is also of reduced complexity due to use of a correlator to provide channel response data to the turbo equalizer. The channel response data is produced by comparing received data comprising a training sequence with a locally produced training sequence. 2 figures
