摘要： In base station side equipment, a control channel for transmitting control information and a communication channel for transmitting information to each mobile station are spread with different synchronizing codes before being superposed by operating a switch to switch the output of an adder over to the output of a synchronizing code generator. Further, a synchronizing code is periodically inserted in a signal by one symbol length and the signal is transmitted over the superposed channel. In a plurality of base station side equipment, moreover, the synchronizing code and its transmission period are equal and the transmission timing is asynchronous and independent. A synchronizing correlator in mobile station side equipment obtains the correlation value of the whole chip phase in a synchronizing code transmission period using the synchronizing code and decides a base station which is transmitting the synchronizing code at the greatest correlating peak position to the closest one and further extracts symbol timing from the peak position.

摘要： A base station transmits, in addition to a pilot channel, signals which are multiplexed with pilot symbols inserted in the respective signals in communication channels. As the transmission of the pilot channel as a reference signal for coherent detection is unnecessary with high power so as to attain high reliability, the pilot channel can be transmitted with low power by means of weight in comparison with the communication channel, so that interference with the communication channel of any other station is reduced. Moreover, accurate coherent detection can be made from the pilot symbol inserted in the communication channel on the mobile station side.

摘要： An X-ray imaging apparatus acquiring a differential phase contrast image of a test object without using a light-shielding mask for X-ray. The apparatus includes an X-ray source, a splitting element configured to spatially divide an X-ray emitted from an X-ray source and a scintillator configured to emit light when a divided X-ray beam divided at the splitting element is incident on the scintillator. The apparatus also includes a light-transmission limiting unit configured to limit transmitting amount of the light emitted from the scintillator and a plurality of light detectors each configured to detect the amount of light that has transmitted through the light-transmission limiting unit. The light-transmission limiting unit is configured such that a light intensity detected at each of the light detectors changes in response to a change in an incident position of the X-ray beam.

摘要： Provided is an X-ray imaging apparatus and a method of X-ray imaging, with which the apparatus can be reduced in size and a with which differential phase image or a phase image with consideration of an X-ray absorption effect of an object can be obtained.A displacement of X-rays that have been split by a splitting element and have passed through an object is measured. The displacement can be measured by using a first attenuation element having a transmission amount that continuously changes in accordance with the incident position of X-rays. At this time, an X-ray transmittance of an object that is calculated by using a second attenuation element having a transmission amount that does not change in accordance with the incident position of X-rays is used.
