Abstract: The communication device extracts frame data originated by the base station and obtains the parameters of using bandwidth, stored in the header of the frame data. Free bandwidth is calculated by subtracting an already used band from the full band of the base station. It is determined whether the free band can accommodate the band that its own terminal desires to use. If it can be accommodated, a network entry sequence is run in order for the terminal to communicate with the base station since communications with the base station is available.

Abstract: A transfer-indication storage unit indicates an address and a data length of data to be transferred by a DMA circuit. An expected value table refers to a transfer indication of the transfer-indication storage unit and stores therein expected values of the address and the data length of the data to be transferred. A transfer-monitoring unit retrieves tag data and a data length of data in a bus. Based on the data length and the tag data notified by the transfer-monitoring unit, a table updating unit updates a start address and the data length in the expected value table. A determining unit determines whether the start address, corresponding to the DMA circuit after data transfer, matches with an end address, and further determines whether the data length has become zero.

Abstract: According to the WDM optical transmission system, for optical signals of respective wavelength in a WDM light propagated through a transmission path, a spectrum component at a center wavelength of each optical signal and a spectrum component in the vicinity of the center wavelength thereof are selectively attenuated by a spectrum correction optical filter, so that the WDM light is transmitted in a state where intensity of sideband components in the spectrum of each optical signal is relatively increased. As a result, even if spectrum width of the optical signal of each wavelength is limited when the WDM light passes through the band-limiting device on the transmission path, degradation of transmission characteristics caused by the attenuation of sideband components is reduced.
