Echo Cancellation: Why It Makes Or Breaks Voice Quality In PHS/DECT
نویسنده
چکیده
PHS/DECT networks are “micro-cellular” radio access systems. Unlike cellular or 3G (third-generation) wireless networks they don’t require comprehensive, expensive supporting network architectures. Instead they inter-work with existing systems, such as PBXs (private branch exchanges), the PSTN (public switched telephone network), cellular networks, and ISDN (integrated services digital network) equipment.

متن کاملGenetic algorithm for Echo cancelling
In this paper, echo cancellation is done using genetic algorithm (GA). The genetic algorithm is implemented by two kinds of crossovers; heuristic and microbial. A new procedure is proposed to estimate the coefficients of adaptive filters used in echo cancellation with combination of the GA with Least-Mean-Square (LMS) method. The results are compared for various values of LMS step size and diff...
متن کاملWhat Makes Whistleblowers So Threatening?; Comment on “Cultures of Silence and Cultures of Voice: The Role of Whistleblowing in Healthcare Organisations”
Whistleblowing is defined by the retaliation that those who speak out receive. Why some organizations find it almost impossible not to retaliate depends more on the properties of the organization than the act of the individual whistleblower. These properties are, to greater or lesser degree, present in all organizations. Not all organizations retaliate against whistleblowers, but the whistleblo...
