Abstract: A terminal detection method that includes a search step, a first acquisition step, a second acquisition step, and a detection step. The search step transmits a response request through broadcast communication and searches a terminal device that exists within a predetermined range. The first acquisition step acquires, from the terminal device, at least specific information of the terminal device. The second acquisition step executes communication with the terminal device based on the specific information acquired in the first acquisition step and acquires second information that indicates a function possessed by the terminal device. The detection step detects that the terminal device has a desired function based on the first information acquired in the first acquisition step and the second information acquired in the second acquisition step.

Abstract: A wireless station device determines whether a carrier to noise ratio of a vertical polarization wave is lower than a first threshold value, determines that a present modulation method for the vertical polarization wave is to be changed to another modulation method having a small multilevel number when the carrier to noise ratio of the vertical polarization wave is lower than the first threshold value, and transmits modulation method information to the facing wireless station device. Further, the facing wireless station device transmits a radio signal to the wireless station device using the modulation method indicated by the received modulation method information for the vertical polarization wave.

Abstract: A wireless communication device avoids unnecessary reduction of transmission capacity of a data signal to ensure the reliability of a pilot signal. A determination unit determines a reception modulation method for a received data signal according to the state of the transmission line. A transmission circuit generates a first pilot signal indicating the reception modulation method determined by the determination unit and, after adding an error correction code, modulates and transmits the first pilot signal. A reception unit receives a second pilot signal indicating a transmission modulation method that is the method for modulating a transmitted data signal. A switching unit, in accordance with the transmission modulation method indicated by the second pilot signal received by the reception unit, switches at least one of the modulation method of the first pilot signal transmitted by the transmission circuit and the redundancy of the error correction code of the first pilot signal.

Abstract: A reference voltage generating circuit receives a power supply voltage and generates a reference voltage. A reference voltage level guarantee circuit generates a sense signal when the circuit senses that a value of the reference voltage has reached a predetermined value.

When the value of the power supply voltage increases and the value of the reference voltage reaches a predetermined value, the voltage comparator circuit operates, and a power ON reset signal is outputted in response to a result of comparison between a divisional voltage and the reference voltage.
