Abstract
A network node for an EGPRS system, arranged to transmit bursts to a receiving node in the EGPRS system, where a burst comprises a training sequence with training information for use by the receiving node. The network node is arranged to use waveforms as said known training sequences, with the shape of the waveform as such conveying the training information. The waveforms are either digital waveforms or analogue waveforms.
Claims28
A network node for an EGPRS system, the network node being arranged to transmit bursts to a receiving node in the EGPRS system, where a burst comprises a training sequence with training information for use by the receiving node, the network node being characterized in that it is arranged to use waveforms as said training sequences, with the shape of the waveform as such conveying the training information.
A network node for an EGPRS system, the network node being arranged to receive bursts from another node in the EGPRS system, where a burst comprises a training sequence with training information for use by the network node, the network node being characterized in that it is arranged to receive, recognize and use waveforms as training sequences in the bursts from the other node and to find and extract the training information in the shape of the waveforms as such.
The network node of claim 9, being arranged to receive said waveforms as digital waveforms.
A method for operating a network node in an EGPRS system, the method comprising transmitting bursts from the network node to a receiving node in the EGPRS system, and inserting into a burst for transmission a training sequence with training information for use by the receiving node, the method being characterized in that it comprises the use of waveforms as said training sequences, and using the shape of the waveform as such to convey the training information.
A method for operating a network node in an EGPRS system, the method comprising receiving bursts from another node in the EGPRS system, where a burst comprises a training sequence with training information for use by the network node, the method comprising recognizing and using waveforms as training sequences in the bursts from the other node, and finding and extracting the training information in the shape of the waveforms as such.
