A packet data communication system includes a control station and a plurality of mobile terminals that communicate on demand with the control station over a wireless link. The control station has a data port for receiving data packtets destined for the terminals, an arrangement for generating a ...
摘要: PROBLEM TO BE SOLVED: To obtain a TDMA/TDD data communication system where a speech wait time for a plurality of slave sets can remarkably be reduced in the case of making a multiple speech between one master set and a plurality of the slave sets.收藏...
Time Division Multiple Access (TDMA) is a digital modulation technique used in digital cellular telephone and mobile radio communication. TDMA is one of two ways to divide the limited spectrum available over a radio frequency (RF) cellularchannel. The other is known asfrequency division multiple ac...
The invention provides TDMA/TDD system data transmission equipment that allows, in data communication between one piece of data transmission equipment and plural (N) pieces of data transmission equipment, multiplex data transmission in one to N with a high data transmission rate, which can be manufa...

Minimizing transmission time in an SS/TDMA system with variable power carriers This paper considers an SS/TDMA system that transmits traffic at variable speeds by dynamically varying the amount of power used. The total amount of power... AJ Hu,GM Engel - AIAA 14th International Communication ...
In a satellite transponder communication system operating in a time division multiple access mode, each earth station transmits data in a burst format. All bursts within a single transponder frame are synchronized to a special reference burst which contains no data communications. A single earth stat...
The invention relates to a data transmission method in TDMA mobile communication system. In a mobile communication system employing a so-called multi-slot access technique, one or more time-slots may
