Abstract: A communication device, a transmission control method, and a transmission control program are provided to construct a communication system with high transmission efficiency by selecting a suitable destination. A transmission buffer(11) has multiple memory regions corresponding to each of multiple destination candidates as destinations of data. A detecting unit detects a data amount stored in each memory region. A destination selecting unit(12) selects one destination among the destination candidates based on the detected data amount. A transmission signal generating unit(13) reads a certain amount of data of the destination selected by the destination selecting unit from the memory region to generate a transmission signal.

Abstract: A retransmitting control circuit, a transmitter, a retransmitting control method, and a retransmitting control program are provided to prevent the increase of the power consumption in the control circuit performing retransmitting control by reducing an amount of processes to compare a retransmitting time and a present time. A retransmitting control circuit includes a recording unit(12), a decoding unit(13), and a control unit. The recording unit(12) is generated to correspond to each data which is a retransmitting object and records retransmitting information having the retransmitting time of the corresponding data in a memory. The decoding unit(13) decodes the retransmitting information from the memory. The control unit performs the retransmitting process of the data corresponding to the corresponding retransmitting information according to a comparison result by comparing the retransmitting time having the longest retransmitting information among the retransmitting information in the memory with present time.

Abstract: A communication system, a transmission device and method, and a reception device and method are provided to solve a problem that although a CPU is in an idle state, it must be initiated to receive or transmit a beacon signal during an almost certain period for each super frame. When the fist information, which is among information included in a beacon signal and is not updated at every certain time, is updated, the first software processing unit processes the information. The first hardware processing unit processes the second information which is updated at a rate of one or more time at the certain time, among information included in the beacon signal. A generating unit generates a beacon signal by adding the second information to the first information. A receiving unit receives the beacon signal. A separating unit separates the first and second information. The second hardware processing unit processes the second information. A determining unit checks whether the first information has been updated. When the first information has been updated, the second software processing unit processes the updated first information.

Abstract: 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.
