摘要： During operation of a secondary communication system, nodes having different channel monitoring capabilities or requirements will cooperatively monitor possible frequencies for transmissions, each node using only a subset of all possible modulation sensing schemes. All nodes will share channel occupancy information to other nodes within the communication system. For example, a first group of nodes may monitor possible frequencies for television transmissions, while a second group of nodes may monitor the possible frequencies for APCO 25 transmissions. A group of nodes may also cooperatively monitor possible frequencies for more than one type of modulation transmission. Channel information will be shared among the nodes.

摘要： In a cognitive radio, a method of establishing an operational policy for use in a Peer-to-Peer (P2P) group, wherein the policy can be described by layers of policy parameters with progressively higher layers having a progressively increasing number of parameters, involves determining that a policy change is to be made from a current policy; requesting policy information from at least one P2P group member; receiving a policy description from the at least one P2P group member; and implementing a change in the lowest layer policy parameter to establish a new operational policy.

摘要： A node of a wireless mesh network assigns a radio frequency (RF) channel for operation by sensing an interference level in a number of RF channels, determining which RF channels are available for use and selecting the available RF channel having the best performance. The node then attempts to communicate with neighboring nodes of the wireless mesh network using the selected RF channel. If communication with a sufficient number of nodes is not achieved, the node selects an available RF channel having the next best performance, and attempts to communicate with neighboring nodes using the selected RF channel. The process is repeated until the node can communicate with a sufficient number of nodes. The selected RF channel is then assigned for node operation.

摘要： Disclosed is a circuit for controlling the activation of a stereo indicator and a tune indicator in an AM stereo receiver. In the preferred embodiment, a pilot tone detector is employed to determine if the input signal is a stereo signal and an AGC is used to detect a preselected improvement in the amplitude of the received signal. A capacitor is charged in response to the stereo or the amplitude condition. When the charge level of the capacitor reaches a first predetermined level, a tune indicator driver is enable to allow a tune detect circuit to drive the indicator. This prevents the tune indication from activating before the receiver is stabilized. When the charge level of the capacitor reaches a second predetermined level, a stereo indicator driver gradually activates the stereo indicator. This prevents sudden power drains from adversely affecting the circuit.

摘要： Communication devices and methods for transmitting and receiving a wideband signal using aggregated discontiguous narrowband channels in a band are presented. During transmission, a fold point is determined in which symmetric free channels are sufficient to transmit the signal. The signal is then synthesized by aggregating the data in the channels and transmitted using the fold point as the up-conversion modulation frequency. During reception, information regarding which channels are being used to provide data signals and which channels are occupied by interferers is received. This information is used to determine one or more fold points as the down-conversion modulation frequencies. The fold points are selected such that an image of each interferer falls on an unoccupied channel or a narrowband channel occupied by another interferer.

摘要： A frequency generation unit is provided that permits a receiver to tune from channel to channel without cycle skipping and in which compensation for phase offset introduced during tuning is provided. The frequency generation unit includes a fractional-N synthesizer, a voltage controlled oscillator (VCO), and a direct digital synthesizer (DDS). The fractional-N synthesizer generates frequencies from the VCO as well as a temperature controlled crystal oscillator. Outputs from the fractional-N synthesizer are supplied both the VCO and the DDS to control the VCO and DDS. The combination of the voltage controlled oscillator and fractional-N synthesizer is perpetually locked. The fractional-N synthesizer is maintained in a locked condition. The VCO output is provided to the DDS. An output from the DDS or from the fractional-N synthesizer forms the output signal of the frequency generation unit.
