A first synchronization signal is used by a master base station and a remote base station in a digital cordless communication system. The master base station generates a second synchronization signal. The second synchronization signal is used to transfer information over a transmission medium between the master base station and the remote base station. The master base station generates the first synchronization signal from the second synchronization signal. Information is transferred over the transmission medium between the master base station and the remote base station using the second synchronization signal. The remote base station generates the first synchronization signal from the second synchronization signal. The first synchronization signal is utilized by the master base station and the remote base station for digital cordless communication.

Efficient generation within a remote base station of a synchronization signal for a cordless communication system

The present invention includes communication systems, communication methods and a method of communicating data within a DECT communication system. One embodiment of the present invention provides a communication system including a radio having a synthesizer operable to generate a carrier signal responsive to frequency data, the radio being configured to communicate a plurality of slots using the carrier signal; a control processor configured to generate control information regarding the slots; and a data processor coupled with the radio and the control processor, the data processor being configured to use the control information to identify a first slot and a subsequent slot responsive to the identification of the first slot, the data processor being further configured to control the output of frequency data to the radio responsive to the identification of the first slot and the second slot.

The present invention provides a radio signal controller comprising: a memory device having a plurality of memory locations individually configured to store at least one radio signal level value; a memory controller operable to sequentially address the memory locations; and a signal generator operable to receive at least one radio signal level value and output a radio control signal responsive thereto. The present invention additionally provides for a radio communication device, radio communication system and method of controlling a radio.

Radio signal controller radio communication device, radio communication

A radio controller arrangement for controlling communication signal timing in a duplex radio-frequency TDMA radio includes a TDMA timer that generates a receive timing signal and a microprocessor circuit. The microprocessor circuit commands the TDMA timer to activate the radio to receive a signal and converts the signal into packets having synchronization and data fields. The TDMA timer synchronizes a beginning of a data collection operation to the synchronization field and locates the beginning of the data field based on the end of the synchronization field. The TDMA timer collects data from the data field until it detects the end of the data field. The TDMA timer then commands deactivation of the radio. The radio controller arrangement may be incorporated into a communication device or used in connection with a method for controlling communication signal timing.
