Patent

CA 2295313

According to the invention, a mobile radio is provided for radio transmission in time-division multiplex frames, which each alternatively have active time slots (Z1) in which data are transmitted and inactive time slots (Z2) in which no data are transmitted. The time duration of the active time slots is in this case twice the duration of the inactive time slots. The mobile radio (1, 2) has a burst mode controller (13) which provides the time-division multiplex frame structure for transmission, and a clock preset device (18), which presets the clock rate for the burst mode controller (13). The clock rate which the clock device (18) presets for the burst mode controller (13) is twice as high during the inactive time slots (Z2) as during the active time slots (Z1).

L'invention concerne un radiotéléphone mobile pour la radiotransmission dans des trames à multiplexage temporel qui présentent en alternance des créneaux temporels actifs (Z1), dans lesquels des données sont transmises, et des créneaux temporels inactifs (Z2), dans lesquels aucune donnée n'est transmise. La durée des créneaux temporels actifs représente le double de celle des créneaux temporels inactifs. Le radiotéléphone mobile (1, 2) présente un contrôleur de mode en salves (13) qui convertit la structure de trame à multiplexage temporel de la transmission, et une unité de spécification de cadence (18) qui spécifie la cadence du contrôleur de mode en salves (13). La cadence ainsi spécifiée est deux fois supérieure pendant les créneaux temporels inactifs (Z2) que pendant les créneaux temporels actifs (Z1).
