Abstract: Parallel ML processing of an analog signal in a RLL-coded channel in which (1) vectors for a current state of the channel and the next state of the channel are computed using Walsh transform vector coefficients of the analog signal; (2) current state vectors and next state vectors and values of vectors precomputed in analog matched filters are used to generate vector scalar products which are compared against preselected threshold values for generating binary decision outputs that are used in digital sequential finite state machines to generate ML symbol decisions; and (3) ML symbol decisions are fed back and used to subtract the intersymbol interference value of the current state vector from the vector of the next state to transform the next state vector into an updated current state vector.

novel combination of monomers. The polyquinoline polymers
comprise repeat units comprising at least one quinoline
nucleus and at least one ether linkage and having as end
groups either fluoro groups or hydroxy groups or a

nucleus, a diol monomer provided in the form of its bis-oxide
salt, or in the presence of a base capable of deprotonating
the diol and reacting the difluoro and diol monomers together
in a dipolar solvent to form the polyquinoline polymer. In
an alternative embodiment, the polyquinoline polymers of the
present invention are formed by reacting a fluoro hydroxy
monomer comprising a quinoline nucleus containing one
activated fluoro group and one hydroxy group in the presence
of a base and a dipolar solvent to form said polymer. In yet
another alternative embodiment, the polyquinoline polymer is
formed by providing a monomer which comprises a quinoline
nucleus containing one activated fluoro group and one hydroxy
group and treating the monomer with a base to form an oxide
salt and reacting the monomer salt in a dipolar solvent to

Abstract: The transmission method involves providing identical calculation models (4) on the transmitter (1) and receiver sides (2). For identical input data, the models provide identical output data. The respective models are formed according to the characteristics of a transmission side data generating system. The method further involves time synchronous calculation (8) of new updated values simultaneously at the transmission and reception sides. These values are compared (5) at the transmission side with the values of the data generating system, e.g. a measurement sensor (6). When deviations between the transmission side measurement value and calculation value lie outside a fixed tolerance, a new, updated model parameter is determined. At least this parameter is transmitted (9) to corresponding models at the receiver side. Further, a new calculation is made of the receiver side value using the received, updated model parameter.
