Abstract: A transmitter, for controlling at least one receiver by intermittently transmitting groups of messages. The transmitter includes a controller arranged to provide intermittently groups of messages for transmission. Each of said groups includes a plurality of messages in series and separated by time intervals, wherein each of the plurality of messages in a group includes control information such that control of the receiver can be effected by reception of any one of the plurality of messages in the group. The invention increases the efficiency with which control messages can be transmitted without markedly increasing the power consumption of transceivers in a radio frequency network.

Abstract: The present invention relates to a method and a device for data extraction from a data stream containing at least one data packet. First, comparing a bit stream derived from a received digital data stream with an expected bit sequence is performed by packet detector to determine a correlation value (CorrVal) for detecting a data packet. Then, a data extraction unit is started for data extraction when the correlation value (CorrVal) exceeds a threshold value (CorrThres) indicating that a data packet has been detected. Therefore, comparing the received bit stream with the expected bit sequence to determine a new correlation value (CorrVal) is continued by the packet detector. Finally, restarting data extraction is initiated by a sync-control module when the new correlation value (CorrVal) exceeds the form correlation value (MaxCorrVal).
