Embodiment Construction

[0029] exist figure 2 In , the general structure of a communication device 1 for transmitting and receiving control data bursts and user data bursts in a digital telecommunication system according to the present invention is shown. This communication device 1 can be a mobile terminal or a base station or a part of a mobile terminal or a base station of a telecommunication system. This communication device 1 comprises an antenna 2 for receiving data bursts from the transmitting side, e.g. a base station of a telecommunication system, the received data bursts being supplied to high frequency means 3 for down-converting the received high frequency bursts into a baseband signal, This down-converted signal is supplied to IQ demodulation means 4 where these signals are demodulated to derive a data sequence and supplied to correlation means 5 for autocorrelating this data. After autocorrelation, this autocorrelation result is supplied to identification means 7 for identifying the t...

Abstract

The present invention relates to a communication device(1) for transmitting and receiving control and user data bursts in a digital telecommunication system, with receiving means(2, 3) for receiving data bursts including bursts of a first type and bursts of a second type different from said first type; correlation means(5) for auto-correlating data of received data bursts and outputting an auto-correlation result; and recognizing means(7) for recognizing the type of a received data burst on the basis of a phase value of the auto-correlation result of the training sequence of the data burst. Thereby, the present invention enables a simple and cheap implementation and a distinction between different types of data bursts is possible. Particularly, the traffic direction can be distinguished in an easy way.

Description

technical field [0001] The present invention relates to a communication device for transmitting and receiving control data bursts and user data bursts in a digital telecommunication system and to a method for distinguishing a first type of data burst sent from a first communication device in a digital telecommunication system A method of bursting with a burst of data of a second type different from the first type transmitted from the second communication device. The communication device of the present invention may be a base station or a mobile terminal of a telecommunication system. The first communication device and the second communication device may be respectively a base station and a mobile terminal, or two mobile terminals directly communicating with each other. The invention is particularly capable of distinguishing the traffic direction of received data bursts. Background technique [0002] In digital wireless telecommunication systems, one base station usually se...
