ABSTRACT:
A decision feedback equalizer device and method for the block transmission of information symbols in which the received noise-affected observation samples are subjected to a whitening of the noise so as to generate whitened-noise observation samples. The current symbol is detected from earlier decided symbols and whitened-noise observation samples. Block transmission of information symbols can thus be performed over a distorting channel in an atmospheric, ionospheric or other environment towards fixed or mobile receivers.
