The Quantum Distribution of the Envelope of a Quasi-Harmonic Signal in Gaussian Noise

R. L. Stratonovich


Abstract: The characteristic function of the square of the envelope of the quantum quasi-harmonic signal $x(t)$ is found by double integration in the $x$-representation according to the function $\varphi\sqrt\lambda=\mathrm{Sp}(e^{-\beta\mathrm{H}}\rho)$
