Abstract
The electrical signal contains signal information and redundancy information for the signal information determined from the signal information. A dependability degree is approximated from the electrical signal for forming at least one signal value, and the signal value is determined dependent on the dependency degree. This ensues in that a target function that contains a model of a transmission channel is optimized, and the optimization ensues upon employment of the target function.

A method for determining at least one digital signal value from an electrical signal transmitted via a transmission channel, said electrical signal having signal information and redundancy information for said signal information determined from said signal information, the method comprising:
- optimizing a target function having a model of a transmission channel via which said electrical signal was transmitted;
- approximating a dependability degree for forming a digital signal value from said electrical signal based on said optimized target function;
- and
- determining said digital signal value dependent on said dependability degree, wherein
- the model is a non-linear regression model of said transmission channel and
- the electrical signal is a systematic block code.
An arrangement for determining at least one digital signal value from an electrical signal transmitted via a transmission channel, said electrical signal having signal information and redundancy information for said signal information, said arrangement comprising:
- a computer unit having a processor and a memory including a program comprising
- optimizing a target function having a model of a transmission channel via which said electrical signal was transmitted;
- approximating a dependability degree for forming a digital signal value from said electrical signal based on said optimized target function;
- and
- determining said digital signal value dependent on said dependability degree, wherein
- the computer unit program is a non-linear regression model of said transmission channel, and
- the electrical signal is a systematic block code.
