Abstract: A method and apparatus that allows a telecommunications system using cdma2000 1X to easily migrate to using cdma2000 3X. In other embodiments, the invention provides for better spectrum management, allows concurrent usage of a standard cdma2000 1X reverse link with a cdma2000 1X time-division-duplexing (TDD) reverse link, and provides for hardware supplementation - as opposed to total replacement - when additional services are added to an existing code-division-multiple-access (CDMA) system.

Abstract: An apparatus and method for performing speech signal compression, by variabl e rate coding of frames of digitized speech samples (10). The level of speech activity for each frame of digitized speec h samples is determined and an output data packet rate is selected from a set of rates based upon the determined level of frame speech activity. A lowest rate of the set of rates corresponds to a detected minimum level of speech activity, such as backgrou nd noise or pauses in speech, while a highest rate corresponds to a detested maximum level of speech activity, such as alive vocalization. Each frame is then coded according to a predetermined coding format for the selected rate wherein each rate has a corresponding number of bits representative of the coded frame. A data packet is provided for each coded frame with each output data packet of a bit rate corresponding to the selected rate.

Abstract: UN METODO Y UN SISTEMA (16) POR EL QUE LOS DATOS DE UN PARAMETRO REPRESENTATIVO DEL LENGUAJE CODIFICADO SE ORGANIZAN EN PAQUETES DE DATOS PARA LA TRANSMISION, REDUCIENDO ASI EL IMPACTO DE LOS ERRORES INDUCIDOS SOBRE EL PAQUETE DE DATOS EN EL CANAL DE TRANSMISION. UN PAQUETE DE DATOS SE CONSTRUYE CON CIERTA MAYORIA DE BITIOS PERCEPTIBLEMENTE SIGNIFICANTES DE LOS DATOS DEL PARAMETRO EN EL PRINCIPIO DEL PAQUETE DE DATOS. LO SIGUIENTE EN EL PAQUETE DE DATOS SON MENOS BITIOS PERCEPTIBLEMENTE SIGNIFICANTES DEL MISMO DATO DEL PARAMETRO. OTRO DATO DE PARAMETRO SIGUE DESPUES EN EL PAQUETE DE DATOS. INTERCALADO EN EL PAQUETE DE DATOS SIGUE LA MAYORIA DE BITIOS PERCEPTIBLEMENTE SIGNIFICANTES DEL PRINCIPIO DEL PAQUETE DE DATOS, QUE SON LA MAYORIA DE BITIOS PERCEPTIBLEMENTE SIGNIFICANTES DE OTRO DATO DE PARAMETRO. UN CODIGO DE COMPROBACION DE PARIDAD SE PROCESA DESDE LA MAYORIA DE BITIOS PERCEPTIBLEMENTE SIGNIFICANTE EN EL PAQUETE DE DATOS Y TAMBIEN INTERCALADO EN EL PAQUETE DE DATOS SIGUE LA MAYORIA DEBITIOS PERCEPTIBLEMENTE SIGNIFICANTE DEL PRINCIPIO DEL PAQUETE DE DATOS.

Abstract: A method of adding hangover frames to a plurality of frames encoded by a vocoder, the method comprising: detecting that a predefined number of successive frames has been encoded at a first rate; determining that a next successive frame should be encoded at a second rate that is less than the first rate; and selecting a number of successive hangover frames beginning with the next successive frame to encode at the first rate, the numbering dependent upon an estimate of a background noise level.
