    Abstract: PROBLEM TO BE SOLVED: To provide a wireless back end circuit that includes a signal processing unit to receive an intermediate frequency signal which includes information to be modulated. SOLUTION: The wireless back end circuit processes an intermediate frequency signal and provides the output of the information to be modulated. The wireless back end circuit includes a plurality of control registers and receives digital information given from the outside of the wireless back end circuit. Furthermore, the wireless back end circuit includes a signal optimizing circuit, which has an output that is coupled with a signal processing unit and the registers to revise how to process the intermediate frequency signal by the wireless back end. Moreover, the wireless back end circuit includes an analog interface coupled with the signal processing unit and converts analog information from the signal processing unit into information for a digital processing unit.

    Abstract: PROBLEM TO BE SOLVED: To provide a radio back end circuit provided with an integration circuit and a first variable voltage converting circuit having a signal input coupled with the output of the integration circuit. SOLUTION: This circuit is provided with a first variable low-pass filter, a second variable voltage converting circuit and a variable attenuator. These members of the radio back end circuit are coupled so as to communicate, noises are reduced in radio communication and the control of signals and of a receiving range is improved on certain fixed conditions.

    Abstract: A radio back-end circuit that includes a signal processing unit which receives an intermediate frequency signal containing modulated information. The radio back-end circuit processes the intermediate signal and provides an output representative of the modulated information. The radio back-end circuit includes a plurality of control registers for receiving digital information provided external to the back-end circuit. Also included is a signal optimization circuit, coupled to the plurality of registers, having an output coupled to the signal processing unit for modifying how the radio-back-end processes the intermediate frequency signal. In addition, an analog interface, coupled to the signal processing unit, is included which converts analog information from the signal processing unit to digital processing unit information.

    Abstract: 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.

    Abstract: A method and apparatus for allowing communication units (100) to utilize non-licensed spectrum is provided herein. In particular, when a radio (100) determines a need to transmit within non-licensed spectrum, the radio (100) searches for a beacon being transmitted (303). The beacon identifies a priority of the current user of the non-licensed spectrum (305). If the radio's (100) priority is higher than the current user of the non-licensed spectrum, or if no beacon is heard, the radio (100) may begin transmitting within the non-licensed spectrum (311). As part of the radio's (100) transmission, a beacon will be broadcast by the radio (100) identifying the radio's (100) priority.
