摘要： It is aimed at performing an inverse FFT for ranging and efficiently estimating channel characteristics of a time response. It is highly possible that the UWB standardization adopts OFDM systems. A transmission estimation section inevitably acquires estimation values for a frequency region. The ranging is a representative feature of the UWB and requires channel estimation values for time response. For this reason, an inverse FFT needs to be performed for conversion. Frequency region smoothing means is used for time response limitation to prevent additional large FFTs from being provided for the ranging. It is therefore possible to acquire time responses using fewer FFT points than for ordinary data reception.

摘要： In a jig for inspecting a device provided with at least a radio frequency signal terminal and an earth terminal, a metal block is formed with a through hole extending in a first direction. A contact probe is inserted into the through hole. The contact probe is provided with a metal pipe extending in the first direction. A plunger is retractably projected from one longitudinal end of the metal pipe to be brought into contact with the radio frequency signal terminal. At least two dielectric ring members are provided on an outer periphery of the metal pipe, and fitted with the through hole while forming a gap between the outer periphery of the metal pipe and an inner wall of the through hole, in order to form a coaxial path in which the contact probe serves as a core conductor and the metal block serves as an external conductor. A diameter of the through hole and a diameter of the dielectric ring members are selected such that the coaxial path has a predetermined impedance relative to the radio signal frequency terminal.

摘要： A communication resource allocation method and apparatus services, in even the code division multiple access method (CDMA) considered to be suitable for radio transmission using mobile stations such as a cellular phone, a strict orthogonal relationship, so that received signals can be separated from each other completely. This reduces the problem whereby other mobile stations are interfering sources. It also reduces the problem whereby if an application band width for use is defined, the other band widths cannot be applied. The multi-carrier modulation section places a plurality of carriers continuously within a preliminary allocated band and modulates the individual carriers separately. An adder synthesizes a plurality of the carriers modulated by the multi-carrier modulation section. An antenna transmits a synthesized output from the adder.

摘要： A communication system that can satisfactorily communicate with a mobile station by a transmitter and receiver of a simple arrangement, wherein a plurality of carriers having different frequencies are transmitted simultaneously and data is transmitted on the basis of a phase difference between the carriers. Also, the carriers are multiplied with a predetermined time waveform and transmitted, so that a reception side receives data by use of a time waveform narrower than the above time waveform.

摘要： In a radio communication system for performing digital radio communications by using time-division multiplexed time slots, a first personal station receives its user's speech through the microphone, converts it into audio data, and transmits them on time slots to a second personal station. On the other hand, the first personal station receives non-audio data from the data processor connected with the second personal station and stores. When the audio data amount inputted to the first personal station in a unit time period is lower than a threshold and the communications between the first personal station and the second personal station are put in a silence condition, the first personal station transmits non-audio data on times slots to the second personal station. When the communications return to a sound condition, audio data transmission is restored. Whether each time slot carries audio data or non-audio data is designated by an identifier which is written in a predetermined field of each time slot.
