5. These considerations give rise to the following logical causal chain of factors that has led to
the crisis in the information transmission theory development:
Representation of the signal receiving process under the noise influence as probabilistic and
statistical problem;
↓
The usage of coding as the best realization of the maximum likelihood method;
↓
Appearance of physical limit rates – channel capacity.
As shown in this paper, we cannot break the chain represented above:
− it is impossible to exceed the capacity without abandoning the maximum likelihood method;
− it is impossible to abandon the maximum likelihood method when the work of receiver consists
in solving the probabilistic problem.
Thus, the root of the considered problems is a probabilistic approach to receiving signals under
the noise influence and even the most ambitious assumptions give no alternatives to it. However, it
is not so. We do use not all the opportunities, which the nature offers for handling noisy digital signals
in continuous channels. However, this will be discussed in the further publications.
