摘要： PROBLEM TO BE SOLVED: To provide a radio receiving device for a moving body, which can receive a signal having a frequency that a user desires as much as possible according to a reception state or the like. SOLUTION: The user sets and registers frequency information on a first desired view frequency in a frequency information storage unit 9 by using a user interface such as an operation input unit 10. When it becomes difficult to view because of deterioration in reception signal quality etc., the user indicates switching of the view frequency through the operation input unit 10 to switch the frequency to another view frequency. At this time, a frequency information switching unit 8 performs the switching between the frequency of contents being currently viewed and the first desired view frequency registered by the user in arbitrary timing, a signal quality decision unit 7 decides the reception signal quality of the first desired view frequency, and when the reception signal quality is improved, a notification unit 13 reports that effect to the user.

摘要： PROBLEM TO BE SOLVED: To solve the problems that a conventional polynomial approximation system digital pre-distortion compensation circuit is the circuit where it is advantageous to have a small memory amount but approximation is not performed by a finite polynomial equation causing reduce of a distortion compensation amount in the case of a power amplifier with strong nonlinearity, and that a conventional LUT system digital pre-distortion compensation circuit is the circuit where the distortion is compensated even in the case of the power amplifier with strong nonlinearity since the characteristic itself of the power amplifier is discretely stored in a memory but the memory amount is increased causing delay of a reaction time with the increase of a memory calling time. SOLUTION: A section with the strong nonlinearity and a section without it are extracted concerning the input level-Gain characteristics and the input level-phase characteristics of the power amplifier. An LUT system is applied to the section with the strong nonlinearity and a polynomial approximation system is applied to the section without it. Consequently, the digital pre-distortion compensation circuit is obtained, where the distortion compensation amount is large, the memory amount is reduced, and an operation is performed at high speed even in the case of the power amplifier with the strong nonlinearity.

摘要： PURPOSE:To reduce the power consumption by not using any transistors but using a chopper type switching power source of high conversion efficiency. CONSTITUTION:When the ambient temperature detected by a thermistor 45 is different from a reference temperature, the internal resistance value of the thermistor 45 is changed in accordance with this temperature difference. A voltage control part 50 outputs a voltage corresponding to the internal resistance value to a voltage controlled power source 51. This power source 51 synthesizes the voltage with a triangular wave and changes the duty ratio of this voltage value to output a voltage or pulse width modulation. This voltage is applied to the negative terminal of a Peltier element 10. A constant voltage source 46 outputs a fixed voltage to a constant voltage power source 52, and the power source 52 outputs a voltage of pulse width modulation whose duty ratio is fixed to 50% with respect to the fixed voltage. The voltage of pulse width modulation is applied to the positive terminal of the Peltier element.
