    摘要: A method and apparatus for improved mobile radio telecommunications employs the transmission of a pilot reference signal within the coherence band of the modulated carrier wave. The receiver in this system uses instantaneous phase estimation techniques of the pilot and carrier received waveforms to provide immunity from phase distortion introduced by the channel.

    摘要: The systems and methods for deploying VoIP telecommunication services. The systems include at least one service package that has a set of instructions for carrying out, hosting and/or deploying a VoIP telecommunications service. The system also includes a runtime environment, or process, that is capable of processing instructions stored in the one or more service packages for the purpose of carrying out the VoIP service deployment. The system further includes one or more adapters, each of which is capable of interfacing the system to the external network environment through which the communication service will be deployed. Optionally and preferably the system may also include an integrated development environment for allowing a user to develop a service package which can be executed within the runtime environment for directing the external network, through the adapters, to implement the user developed service.

    摘要: The model adaptation system of the present invention is a speaker verification system that embodies the capability to adapt models learned during the enrollment component to track aging of a user's voice. The system has the advantage of only requiring a single enrollment for the user. The model adaptation system and methods can be applied to several types of speaker recognition models including neural tree networks (NTN), Gaussian Mixture Models (GMMs), and dynamic time warping (DTW) or to multiple models (i.e., combinations of NTNs, GMMs and DTW). Moreover, the present invention can be applied to text-dependent or text-independent systems.

    摘要: A system for collecting and aggregating data from network entities for a data consuming application is described. The system includes a data collector layer to receive network flow information from the network entities and to produce records based on the information. The system also includes a flow aggregation layer fed from the data collection layer and coupled to a storage device. The flow aggregation layer receiving records produced by the data collector layer and aggregates received records. The system can also include an equipment interface layer coupled to the data collector layer and a distribution layer to obtain selected information stored in the storage device and to distribute the select information to a requesting, data consuming application.
