ABSTRACT:
The demodulation process of a wireless data transmission system using multi-level symbols makes use of templates corresponding to each of the possible symbol transitions, so that knowledge of previously decoded symbols can be used to decode the next one. An estimation and correction loop provides for initial estimation of the values of a plurality of consecutive symbols, and error estimates are made for the estimated initial values of the symbols and for one or more alternative values, a final estimate being determined to minimize the total estimated error.
