Abstract
A method is provided for channel coding a parameter whose values are correlated with one another to different extents and according to which code words with better distance properties are at least partially associated with the more strongly correlated values of the parameters, and code words with weaker distance properties are at least partially associated with the more weakly correlated values of the parameter.

A method for channel coding of a parameter, the method comprising the steps of:
- closely correlating, in a manner which is one of temporal and spatial, values of the parameter to different extents;
- mapping the values of the parameter to code words;
- providing that the code words be at different distances from each other;
- and
- mapping the values of the parameter to code words such that values of the parameter which are relatively closely correlated to each other are mapped to code words which are at relatively great distances from each other.
A method for channel coding of a parameter, the method comprising the steps of:
- forming a pair of values from a first value of the parameter and a second value of the parameter, wherein the second value of the parameter at least partially differs in how strongly the second value depends on the first value;
- mapping the values of the parameter to code words;
- providing that code words be at different distances from each other;
- and
- mapping the values of the parameters to code words such that a pair of values including a first value and a second value, for which the second value is more strongly dependent upon the first value, is mapped to the code words which exhibit greater distances to each other than a pair of values for which the second value is less strongly dependent on the first value.
A method for channel coding of a parameter, the method comprising the steps of:
- correlating values of the parameter, the correlation being one of temporal and spatial;
- assigning, at least partially, code words with better distance characteristics to more closely correlated values of the parameter;
- and
- assigning, at least partially, code words with worst distance characteristics to less closely correlated values of the parameter.
