摘要： A digital two-way radio communication system including first and second radio stations. Each radio station includes an antenna, a data transmission unit, a data reception unit, and a switching circuit. Both radio stations are radio-connected by a single frequency. When a first data transmission unit transmits data to the second radio station, a first switching circuit in the first radio station forms a transmission path between the first data transmission unit and a first antenna, and a second switching circuit in the second radio station forms a reception path between a second antenna and a second data reception unit in the second radio station, or vice versa.

摘要： A frequency synthesizer having an intermittently operated PLL circuit in which power is intermittently applied to a prescaler to reduce power consumption. The PLL circuit is operated such that fluctuations in the frequency synthesizer output frequency do not occur. This stability in the output frequency results from selectively providing signals to the phase comparator within the PLL circuit only during a time period beginning after power is applied to the prescaler and ending before power is removed from the prescaler.

摘要： Disclosed are an error-detecting encoding apparatus for creating parity bits by error-detecting encoding processing, appending the parity bits to an input data string and encoding the data string, and an error-detecting decoding apparatus for detecting error using these parity bits. Data segmenting means segments an input data string, which is to undergo error-detecting encoding, into a plurality of sub-data strings, dividing means divides the segmented sub-data strings by a polynomial, which is for generating an error-detecting code, and calculates remainders, converting means applies conversion processing, which conforms to a segmentation position of the sub-data strings, to the remainders on a per-remainder basis, and combining means combines converted values, which have been obtained by the conversion processing, and outputs parity bits. An encoder appends this parity to a data string, and a decoder detects error using this parity.

摘要： A transmission circuit transmits a connection request including a “signature” to a base station. The demodulator demodulates the AICH for transmitting a notification corresponding to the connection request. When requested communications are enabled, the AICH transmits the “signature”. A multiplier multiplies a demodulation signal by the “signature”. A voltage computation unit converts the output of the multiplier into a voltage value. An integrator integrates the voltage value computed by the voltage computation unit for each received symbol for the respective symbols corresponding to the “signature”. A threshold generation unit adaptively selects one of a threshold determined based on the noise of a transmission path or a threshold determined based on the receiving power. If the output of the integrator is larger than the selected threshold, it is determined that the communications have been enabled.

摘要： In a mobile communication system for authenticating a communicating party when communication is performed between a mobile terminal and a device on the side of a network, the mobile terminal, upon receiving a request signal requesting operation execution from the network device, sends the network device an authentication request signal in order to determine whether the request signal is a request signal from an authorized network device, and performs an authentication operation. The network device executes an authentication operation based upon the authentication request signal received from the mobile terminal and sends a result of the authentication operation to the mobile terminal. The mobile terminal compares the result of its own authentication operation and the result of the authentication operation sent from the network device and executes an operation that is in accordance with the request signal only if authentication that the network device is an authorized network device is obtained based upon agreement of results.
