Abstract

We investigate reliability of information transmission in the number-state model for fermionic (electronic) channel and consider a special case when the signal excites particles that are initially in the vicinity of Fermi energy _f ("thermal" fermions) and a quantum of signal energy is much greater than kT₀, where k is Boltzman constant and T₀ is the environment temperature. Assuming that probabilities of exiting the particles are equal to 1, populations of states with energies _F kT₀ are equal to 0, single-particle states in the vicinity of _f are equidistant and using the linear approximation of the distribution function in the vicinity of Fermi energy one can present the probability p of transmission of signal that excites n fermions as p(n) exp(n/2).
