摘　　要：This paper deals with the analytical derivation of phasor-domain statistical properties of crosstalk in random wire cables due to the superposition of several sources of electromagnetic interference.In this study,statistical characterization of crosstalk in cable bundles,which is available in literature for the case of one source of interference,is extended to the case of several sources operating simultaneously.The superposition of crosstalk effects is analysed in statistical terms,also taking into account the correlation between crosstalk contributions.A further random contribution,which is included in the proposed statistical model,is given by the phase relationship between the sources of interference.Analytical approximate expressions for the crosstalk mean value,variance,and probability density function are derived as functions of the cable bundle features and sources.This paper deals with the analytical derivation of phasor-domain statistical proper- ties of crosstalk in random wire cables due to the superposition of several sources of elec- tromagnetic interference. In this study, statis- tical characterization of crosstalk in cable bundles, which is available in literature for the case of one source of interference, is extended to the case of several sources operating simul- taneously. The superposition of crosstalk ef- fects is analysed in statistical terms, also tak- ing into account the correlation between cros- stalk contributions. A further random contribu- tion, which is included in the proposed statis- tical model, is given by the phase relationship between the sources of interference. Analytical approximate expressions for the crosstalk mean value, variance, and probability density func- tion are derived as functions of the cable bun- dle features and sources.
