Estimating the term…
In a digital channel of a digital wireless communication system including at least one mobile station, at least one base transceiver station in communication with the mobile station, a transcoder configured to provide a signal conversion between vocoder frames and pulse code modulation, and a mobile switching center for interconnecting the digital wireless communication system to a public switched telephone network, a method and apparatus for determining a fault in the digital channel is disclosed. The method includes generating a first set of vocoder input parameters from a speech input signal, and generating a second set of vocoder input parameters from an output signal substantially equivalent to the speech input signal as it is received at a mobile station via the digital channel. The method further includes calculating a metric based on the first and the second set of vocoder input parameters, and subsequently determining a fault in the digital channel using the metric.
In digital wireless communication system, the digital wireless communication system including a plurality of elements comprising a plurality of mobile stations, a plurality of base transceiver stations, each of the plurality of base transceiver stations in communication with at least one of the plurality of mobile stations, a transcoder configured to provide a signal conversion capability between vocoder frames and pulse code modulation, and a mobile switching center for interconnecting the digital wireless communication system to a public switched telephone network, a method for determining a fault in a digital channel of the digital wireless communication system, the method comprising:
An apparatus for determining a fault in a digital channel of a digital wireless communication system, the apparatus comprising:
