Summary:
Coupled electron wave guide can be used as a frequency discriminator in the receiver part of a terahertz-band frequency shift keying communication system. However, failure of the discriminator arises because of quantum uncertainty. In this study, we examine the error reduction by direct sequence spread spectrum technique. We have created a mathematical model of the frequency discriminator based on stochastic quantization for quantum mechanical systems. By using the model, we confirmed that the data transmission error decreased with the spreading code length.
