    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： For the purpose of efficient transmission based on the UWB system, first and second baseband waveforms are generated at a cycle equivalent to an integral multiple of a carrier to have a specified phase difference from each other. The first baseband waveform is multiplied by the carrier and a first transmission data sequence to acquire a first transmission waveform. The second baseband waveform is multiplied by a phase shifted carrier and a second transmission data sequence to acquire a second transmission waveform. The first transmission waveform is mixed with the second transmission waveform to acquire a transmission signal. The transmission signal is transmitted as a π/2 shift BPSK signal to transmit a UWB signal. Selecting the baseband waveforms and the carrier makes it possible to configure the transmission band and easily provide division multiplexing transmission.

    摘要： Multi-carrier transmission is performed without inserting a repetitive signal into guard interval periods. A transmitter provides guard interval periods by using a null signal to save transmission power and prevent the deterioration of the SN ratio. Delayed waves at the head of each received symbol cause high-frequency waves to occur and carriers to interfere with one another. Accordingly, a receiver adds a component following each received symbol to a delayed-wave component at the head of the received symbol. As a result, the delayed-wave component at the head of the received symbol and the added component become continuous in wave form and subcarriers do not interfere with each other.

    摘要： A method of forming a thin-film including a capability to remove contaminants from the formed thin-film and/or a substrate on which the thin-film is formed using alcohol. The method includes allowing a substrate holder to support a substract. A first mixture is produced by mixing a condensation polymer containing an element of metal oxide compound and alcohol. Then second mixture is produced by mixing supercritical fluid or liquid carbon dioxide and the first mixture. A thin film is formed by applying the second mixture on a surface of the substrate. After forming the thin-film, the substrate is cleaned by applying alcohol to upper and lower surfaces, preferably the whole upper and lower surfaces, of the substract. The thin-film is crystallized by heating, and the crystallizing may include applying oxygen in a crystallizing chamber. Soft X-rays may be applied to the substrate, during the forming of the thin-film on the surface of the substrate.

    摘要： A communication apparatus capable of reducing the amount of communication with other communication apparatuses is provided, wherein a content signal of a popular program is broadcasted in advance from a broadcast base station to terminals and stored in a memory of each. In a terminal, when a content signal specified by a play instruction signal is stored in the memory, the content signal is read from the memory. On the other hand, when it is not stored in the memory, the terminal requests the specified content signal from the cellular base station via a cellular network and receives the specified content signal.

    摘要： In a communication method, even when the same channel is used to perform another communication based on the time division multiple access, a signal can avoid continuously suffering interference from the other communication. Idle slots (I) which are not used for communication are inserted between frames at random to change the period of time slots (TS0 to TS3) at random and moreover, a transmission signal is transmitted at timing of time slot (TS0) which is assigned to its own station, out of time slots of which the period is changed at random, thereby even when the same channel is used to perform another communication based on the time division multiple access, it is possible to avoid continuous agreement of the transmission timing with the other communication, so that it is possible to prevent continuous reception of communication interference from the other communication.
