摘要： A tuner unit (1) generates a local oscillation signal for multiplication by a received first IF signal and then for conversion in frequency, and converts the frequency-converted signal into a base band signal. A demodulation unit (2) detects a demodulated data signal level for reporting to a control unit (3). The control unit (3) compares the signal level reported from the demodulation unit (2) with a reference value stored in a storage unit (4), and, when the signal level is below the reference value, has the tuner unit (1) change an oscillation frequency of a local oscillation signal used for frequency conversion of the first IF signal and selects a channel in the next frequency range. Therefore, all the broadcasting bands can be scanned in a short time for a quick channel selection and time required before starting a service can be reduced.

摘要： A method and apparatus include determining for use with a user equipment a measurement configuration, which includes at least information on a frequency location of synchronization signals, a carrier frequency value, and a measurement bandwidth. The measurement configuration is transmitted to the user equipment by higher layer signaling, where the higher layer signaling is above the physical layer. One or more synchronization signals are transmitted on the frequency location, from which a first identity value can be determined. A broadcast channel is transmitted to the user equipment from which a second identity value can be determined, the broadcast channel including a first reference signal based on the first identity value. A second reference signal based on the first identity value, the second identity value, the frequency location of synchronization signals, the carrier frequency value, and the measurement bandwidth is transmitted.

摘要： A method for scanning a frequency band for producing a service plan. The method parallelises the scanning by dividing the analysis into two steps: an exploration step for the purpose of detecting channels or frequencies carrying services; and an analysis step for extracting detected channels from program information in order to supply a service plan. Each of the steps is performed by multiple task instances. These tasks share the band to be explored and synchronise, for one same step, via semaphores and, for an inter-step communication, according to a producer/consumer principle.

摘要： A wireless network includes a tunable RF transmitter in wireless communication with a master node to transmit at a first slave frequency; a tunable RF receiver in wireless communication with the master node to receive at a second slave frequency; and an RF oscillator to communicate with the RF receiver and the RF transmitter an RF oscillator frequency to determine and tune the first and second slave frequencies. The RF oscillator is configured to receive calibration information including time information or frequency information, or both, from a reference node. The RF oscillator frequency of the RF oscillator is tuned based on the calibration information from the reference node to enable communication between the slave node and the master node at the tuned RF oscillator frequency.

摘要： A radio receiving device, including a positioning module, a radio receiver, a speaker device, and a control unit, and a method of switching frequencies of radio stations are provided. The positioning module obtains a geographic location of the radio receiving device. The radio receiver plays radio information through the speaker device at a first frequency of a radio. The control unit detects a first signal strength of the radio information at the first frequency. When the first signal strength is smaller than a default value, the control unit checks a radio network frequency list according to the geographic location to obtain a second frequency, and detects a second signal strength of the radio information at the second frequency. When the second signal strength is larger than the first signal strength, the radio receiver plays the radio information through the speaker device at the second frequency of the radio.

摘要： A system and method to efficiently use a plurality of ‘receivers’ to monitor a larger plurality of ‘sources’ for audio content. Upon identifying that a source is active, one of the plural receivers is assigned to convey the content to a destination. All other receivers are prevented from monitoring that specific source for the duration of its activity, but continue to monitor the remaining sources. ‘Source’ includes any source of information containing audio content. ‘Receiver’ includes any device capable of selectively conveying such content, including physical switches, hardware or software multiplexers, microphones, radio receivers, or any other means of obtaining such content.

摘要： In a radio communication system in which multiple bands or a plurality of different radio frequencies are used, a different radio transmission method is used in each band or at each radio frequency. For example, by transmitting data using radio formats which are different in each band or at each radio frequency, the radio transmission method is made different in each band or at each radio frequency. In order to vary the radio format, (1) the pilot length is varied at each radio frequency; or (2) the pilot interval is varied at each radio frequency; or (3) the guard interval length is varied in each band or at each radio frequency; or (4) when multicarrier modulation is used for radio communication in each band, the subcarrier interval for multicarrier transmission is varied in each band.
