Abrégé
(EN)
The invention relates to a method and a device for digital data radiotransmission between a fixed station (1) and at least one mobile station (2, 3) at one or several carrier frequencies (F1, F2, etc.), wherein the data is transmitted in several time slots (Z1, Z2, etc.) according to the time-multiplex technique. A specific amount of time is required to change from one carrier frequency to another carrier frequency using a slow-hopping HF module. The data is transmitted in an active followed by an inactive time slot during which no data is transmitted and which is sufficient for the HF module to program the frequency for the following active time slot. According to the invention, an inactive time slot is shorter than an active time slot.

按照本发明安排了在固定站(1)和至少一个移动站(2,3)之间用多个载波频率(F1,F2,……)中的一个进行数据数字传输的方法和装置,在其中将数据在多个时隙(Z1,Z2,……)上用时分多址方法传输。从一个载波频率到另一个载波频率的变换当使用所谓的慢速超大规模HF模块时需要一个预先规定的时间间隔。数据在工作时隙上传输,在其后各自跟随着一个不工作时隙,在其上没有数据传输,并且这个时隙对于HF模块对于跟在后面的工作时隙的频率编程是足够了。按照本发明不工作时隙在时间上短于工作时隙。
