Self-optimized adaptive algorithms for equalization and carrier recovering application to underwater communications
This paper is concerned with the joint estimation of Doppler shift and equalization in digital communications. After a brief recall of the classical transversal adaptive equalizer. it joint algorithm estimating Doppler and equalizer is presented. The trucking of non-stationarities of the transmission channel is considered and an asymptotically optimum self-optimizing algorithm is proposed. Its performances tire evaluated by simulations. Finally, this algorithm is applied in the case of a real underwater acoustic transmission.
