Abstract: A method of transmitting data across an electronic data communication system comprising a plurality of terminals that can send and receive data in the form of electromagnetic waves to and from at least one of the terminals, which method comprises the steps of: (a) identifying at least one control terminal, at least one target terminal and at least two relaying terminals from the plurality of terminals; and (b) using the control terminal to instruct the at least two relaying terminals to receive and relay data intended for the at least one target terminal, so that the at least one target terminal can receive data directly from at least one terminal and from the at least two relaying terminals, thereby increasing capacity of the system.

Abstract: In mobile communication and radio systems there is a pre-emptive bandwidth allocation by dynamic partitioning the total spectrum available to allow mobile user groups with high priority services to access greater amounts of bandwidth than mobile user groups with low priority services when the network is overloaded.

Abstract: In the Global System for Mobile Communication (GSM), an improvement in estimating the channel impulse response (CIR) is obtained by starting up two channel estimators using the midamble and obtaining channel estimations with split burst. The two estimations are then cross-correlated to obtain the estimated CIR.
