摘要： Channel estimation values of pilot symbols for channel compensation of data symbols in an OFDM receiver can be used, even in cases where FFT extract position differs for each frame. The OFDM receiver is characterized in having a circuit which calculates the amount of phase rotation that is generated by the difference in timing at which the individual symbols are extract as objects of a fast Fourier transform when the fast Fourier transform processing is performed by a fast Fourier transform circuit, and further a circuit which corrects the amount of phase rotation for the channel estimation value determined by a channel estimating circuit.

An extension housing part is separated from the card interface part and not accommodated in the host device. A card loading part is arranged in the extension housing part to load a card that is capable of being inserted to and removed from the extension housing part, into the card loading part. The card loading part is arranged so that a direction of removal of the card accords with a direction of insertion of the card interface part to the host device, and a card slot of the extension housing part and a housing side wall of the host device are mutually opposed in proximity when the card interface part is inserted in the host device.

摘要： A portable electronic device is capable of protecting a camera against impact from outer peripheries of a casing, and clearly indicating the passage of the camera through an image-inversion position. A camera (30) is rotatably installed in a casing (40). Windows (40d, 40e), through which the camera is able to view the outside of the casing and to be operated to rotate by a user, are formed in a front wall (40a) and a rear wall (40b), respectively, of the casing. Each of frames enclosing the windows, respectively, has a part which lies near an outer peripheral side of the casing and which is constituted by a bridge portion (44) connected with the casing. In this construction, all the outer peripheral sides of the camera (30) excepting those corresponding to the front and rear sides of the casing are covered with the casing and the bridge portion (44). As a result, an impact applied to the camera from a peripheral side of the casing adjacent to the bridge portion can be blocked by the bridge portion. In addition, when the camera is rotated to move the shooting or picture-taking plane thereof to the front side or the rear side of the casing, the image on the display becomes dark at a time for example, and hence the user is able to clearly recognize that the camera has passed an image-inversion position. A control part performs prescribed control based on an image of a wall of the casing which is taken by the camera and which lies between the front side and the rear side.

摘要： A signal transmission circuit constructed such that, when a signal of one channel is transmitted in two-divided signal transmission lines, discharge switching elements on two precharged signal transmission lines are controlled by four switching elements (three P-channel MOS transistors and one N-channel MOS transistor). Therefore, when one signal transmission line is at a low level during a signal transmission period, the discharge switching elements of both the signal transmitting lines conduct, leading one signal transmission line to be discharged. This causes the low level signal to be transmitted to the other signal transmitting line.
