A volterra series description of crosstalk interference in communications systems
TLDR
In this paper, a general description of interchannel and intra-channel crosstalk interference created in a communications system is given in the form of a Volterra series expansion of the interference signal in terms of the signal which produced the interference.Abstract:
This paper studies a general description of interchannel and intra-channel crosstalk interference created in a communications system. This description is in the form of a Volterra series expansion of the interference signal in terms of the signal which produced the interference. From it we are able to precisely define the “intelligible” part of the crosstalk. This description also provides us with quantitative measures of the amount of crosstalk created in some communications channel by signals in another channel, as well as a measure (intelligible crosstalk ratio) of the amount of intelligible crosstalk produced. We then consider a particular model for the generation of intelligible crosstalk [or direct adjacent channel interference (DACI)] between two neighboring angle-modulated channels in which the signal in one channel adds to the signal of the second channel, the sum is filtered, and the filter output then passes through an AM-PM conversion device. Using our definition, a simple expression for the intelligible crosstalk ratio for this model is derived in terms of the filter characteristic. We observe that this crosstalk ratio exhibits a number of properties usually associated with DACI.read more

Theory of nonlinear systems
TL;DR: The Taylor-Cauchy transform method has been applied in the analysis of simultaneous nonlinear systems as discussed by the authors, and it is shown that the linear system to the nonlinear system, the input-output crosscorrelation φxy can be shown to be equal to the convolution of system impulse response h1 with the autocorrelation Άxx.

Stable Compensation of Nonlinear Communication Systems
TL;DR: In this article, the authors proposed a post compensator based on Volterra System Theory to reduce the effects of nonlinear distortion in communication channels, where the effects due to the third order nonlinearity are assumed negligible.
