摘要： A wideband multi-tone transceiver system interoperable with Asymmetric Digital Subscriber Line (ADSL) transceiver system, and including a two-step transceiver system having a discrete multi-tone transceiver system and a cosine modulated filter bank (CMFB) transmultiplexer. The two-step transceiver system provides a physically transparent transmission channel to each sub-band signal by minimizing the interference between sub-bands regardless of the transmission channel characteristics. The two-step transceiver system is realized with a comparably simple structure, and the circuit size is drastically reduced by sharing the FFT function with other sub-channels with the maximal utilization of the high-speed circuit when realizing each sub-channel's DMT modulation and demodulation function.

摘要： An apparatus for transmitting and receiving an MPEG data using a wireless LAN includes a first satellite broadcast receiver, a first data controller, a first radio data transceiver, a second radio transceiver, a second data controller and a second satellite broadcast receiver. The first radio data transceiver converts a satellite broadcast signal inputted from the first data controller and transmits it to the second radio transceiver. The second data controller controls a transmission path of the satellite broadcast signal according to determining whether the satellite broadcast signal has been encoded. The second satellite broadcast receiver decodes the satellite broadcast signal inputted from the second data controller to reproduce a moving picture or a voice.

摘要： A direct memory read and cell transmission apparatus for an ATM cell segmentation system having a host CPU is disclosed. The segmentation circuit of the apparatus transfers the address and size for the start of the DMA by the byte unit. When a predetermined information is provided, and a DMA read is requested, the data is transferred through the bus of the word unit such as the PCI interface, and then necessary bytes are obtained for thereby forming a 32 bit word stream, so that the ATM cell of a 32 bit×12 word form and transfers to the lower circuit. Therefore, when the segmentation circuit processes the buffer, all data are computed by the byte unit, and in an application program, the data are not obtained for transmitting the data to the ATM cell, so that it is possible to enhance the processing capability.
