    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: In order cope with a change of the transmitting capacity in a wireless telephone system. A number of transmission channels are set within the transmission frequency band prepared for each base station. When a communication is made between the terminal equipment and the base station through the transmission channels, at least a first transmission channel and a second transmission channel are set as the transmission channel depending on a class of information to be transmitted. The first transmission channel is set to have a fixed transmitting capacity and the second transmission channel is set so that the minimum transmitting capacity may be defined and the transmitting capacity greater than the minimum transmitting capacity may be set depending on the setting condition of the transmission channels within the transmission frequency band prepared.

    摘要: The present invention eliminates a transmission-waiting operation which is unnecessary while accommodating a prioritized traffic. Although a communication station enters a transmission-disallowed state in response to detection of a signal addressed to another station in accordance with medium access control based on CSMA, if the communication station receives a frame transmitted with priority to a local station during the transmission waiting, it cancels the transmission-disallowed state, sends back a frame responding the frame transmitted with priority and effectively operates a transmission prioritized period. The communication station starts a search procedure to perform a processing of evading duplication of the transmission prioritized periods if it judges a possibility of a problem occurring in a time zone in which reception with priority is possible.

    摘要: There is provided a communication apparatus compliant with ultra wide band communication systems for improving resistance to interfering waves in combination with DS-SS (direct sequence spread spectrum). There is provided a training section based on short code spread with the same pattern repeated for each symbol length. Actual communication itself is preceded by coherent channel measurement of a transmission channel by using the training section to specify a length of the short code to be a measurement period and using N cycles of a carrier as a time resolution for measurement. A chip timing is controlled at the time resolution for measurement. At all points given by a time resolution for a measurement period, a measured value is obtained by using the short code to despread A/D-converted values from an input signal based on the chip timing.
