Abstract: A receiver having a digital automatic gain control (AGC) circuit is disclosed for use in a cellular communication system, including a Hierarchical Cellular System. The receiver includes a controller which switches between gain control values depending on system operational mode. In this way, the AGC can be optimized for different types of receive processing operations, e.g., traffic reception and measurement of other channels.

Abstract: A radiocommunication system is described in which DC offset and other slowly varying disturbances which that may impact a signal are suppressed. Exemplary embodiments of the present invention combine a difference circuit, e.g., a FIR filter, with a maximum likelihood sequence estimator, e.g., a Viterbi detector, to implement suppression techniques on binary signals.

Abstract: A method and apparatus for enabling anonymous communications from a first Bluetooth device to a second Bluetooth device is disclosed wherein a temporary identification number associated with the first Bluetooth device is obtained and used in transmissions from the first Bluetooth device to the second Bluetooth device. A temporary identification number provides no clear indication of the particular Bluetooth communications device transmitting messages.

Abstract: Establishing a connection between a paging unit and a standby unit in a channel hopping communications system includes activating the standby unit for an activation time period out of every standby time period. During each activation time period, the standby unit monitors a selected channel for receipt of a paging message. The selected channel is selected from a plurality of channels, and, for each subsequent activation time period, the selected channel is a subsequent one of the plurality of channels as specified by a hopping sequence and an internal clock. A page train is repeatedly transmitted from the paging unit to the standby unit, until a response is received from the standby unit. Each page train includes a plurality of paging messages, each paging message being transmitted on a different one of a subset of the plurality of channels. Selection of a page train for transmission by the paging unit may be based on an estimate of the standby unit's internal clock.

Abstract: In a multi-reuse level cellular communications system, a channel is assigned for use by a mobile unit by first determining whether the mobile unit is a non-enhanced mobile unit or an enhanced mobile unit. Then a determination is made as to the type of communication service being requested. A minimum link quality required by the mobile unit can then be established based on factors that include the mobile unit type and the type of communication service being requested. A base station that has the necessary receiver detection capabilities and transceiver processing capabilities is then selected, and a channel, corresponding to a highest reuse plan, available to the base station is assigned to the call.
