A frequency offset detector is provided which is adaptable to a great frequency offset of one or more carrier waves in an OFDM signal. The frequency offset detector comprises a multiplication circuit which multiplies, by a pseudorandom number bit sequence, a reception signal generated by Fourier transformation of an OFDM modulated signal wherein pilot symbols are dispersed and arranged in accordance with four kinds of patterns and periodically transmitted. Four arithmetic circuits extract the pilot symbols corresponding to the respective patterns from a result of the multiplication by the multiplication circuit for each of the four kinds of patterns and calculate the sum of phase differences among the extracted pilot symbols to output an absolute value. A detection circuit detects a frequency offset on the basis of a maximum value of the absolute values calculated by the four arithmetic circuits. A complex sinusoidal wave is generated on the basis of the detected frequency offset, and the frequency of an input signal is converted thereby, such that the offset of the reception signal can be corrected.

The present invention relates to a lamp lighting technique for lighting multiple lamps safely without luminance irregularities. The present lamp lighting circuit includes multiple closed loops wherein a predetermined number of lamps and the secondary windings of the predetermined number of transformers are connected serially. At least one of the primary windings of the transformers employed for each closed loop is connected to the primary winding of the transformer employed for another closed loop serially. Thus, current of the lamps included in the closed loop is made uniform, and also current is made uniform even between the closed loops by connecting the primary windings of the transformers serially. According to the present invention, with regard to serial connection of the primary windings of the transformers, even if the number of transformers is limited, current uniformity can be propagated to the entirety by subjecting closed loops to catenation consecutively.
