| Outline of Final Research Achievements |
We exemplified a quantum mechanical receiver for Tera-hertz communications and described the detection and discrimination circuits in the receiver by classical mechanical stochastic ordinary differential equations. As a result, we represented the behavior of electrons in the circuits not by wave propagation but by random particle motion like that of electrons in a decoder circuit built of single-electron tunneling devices.
It enabled to model all the circuits in the receiver consistently and simulate whole the receiver circuits simultaneously. To validate the usefulness of the models, we estimated communication quality of a tera-hertz spread spectrum communication system.
