Capacity of voiceband channel with speech signal interference

Research output: Contribution to journalArticlepeer-review

Abstract

An estimation of the capacity of a voiceband channel with speech signal interference and background Gaussian white noise has been made. The solution is based on the fact that over a time interval of tens of milliseconds the speech signal can be considered as a stationary Gaussian process. In such a model the total interference is nonwhite but Gaussian, a situation for which the capacity can be found according to the formulas given in classical literature: The results are important where the voice signal acts as an interference, for example the crosstalk problem in telephone lines, or data over voice (DOV) systems where the speech is transmitted simultaneously with the digitally modulated signal.
