Autocorrelation of output of memoryless nonlinear devices with arbitrary characteristics (Corresp.)
Hossein Ghandeharian, M.P. Beddoes · IEEE Transactions on Information Theory · 1978
An important class of nonlinear devices is that based on the uth-law characteristic. Mathematical methods already employed in the analysis of this class of nonlinearities can be exploited in a rather straightforward manner to obtain ready-made formulas for autocorrelation functions of arbitrary nonlinear characteristics in response to noise plus signal.
