Abstract: A Yule-Walker based, low-complexity voice activity detector (VAD) is disclosed. An input signal is typically noisy speech (i.e., corrupted with, for example, babble noise). In one embodiment, a first initialization stage of the VAD computes an occurrence of a silent period within the input signal and the AR parameters. The VAD could accordingly compute a tentative adaptive threshold and output hypothesis H1 (which means speech is present) during this stage. During the second initialization stage, the VAD generally builds a database of associated values and computes the adaptive threshold accordingly. The second initialization stage could also output tentative VAD decisions based on the tentative threshold computed in the first initialization stage. Finally, the VAD periodically retrains or updates AR parameters, threshold values and/or the database and outputs VAD decisions accordingly.

Abstract: Methods, systems, and media for identifying areas of outbound roaming on a wireless network are disclosed. A roaming-network event record listing roaming events of subscribers of a home network is received. A home-network event record listing network events on a home network is also received. The two records are correlated to identify roaming events and network events having matching caller identifiers and time stamps within a predetermined range. Location data of a network event is adopted as location data for a matching roaming event. A home-network wireless-communications antenna, tower, or station having a service area in which a concentration of roaming events have occurred is identified. The distance of the roaming events from the antenna is determined and distance bands corresponding to that distance are plotted on a map to aid in identifying locations at which outbound roaming has occurred.
