Abstract: PROBLEM TO BE SOLVED: To quickly connect a terminal unit to a base station, while significantly reducing the interference due to a pilot channel by multiplexing together an in-phase channel pilot code and an orthogonal channel pilot code.
SOLUTION: A base station 11 functions as a center device for cells, i.e., a radio network to provide a radio channel to a terminal unit 10 and also to provide various communication channels including a traffic channel, etc., in addition to a pilot channel that is connected to a control unit 12 of the station 11 through wire. The pilot channel provides a pilot codes which construct the radio channel. Then two different sequences are multiplexed together in an in-phase/orthogonal phase mode and used as a single pilot channel. The cells are divided into groups as in-phase pilot channels, and the cells included in each group are divided as orthogonal pilot channels. Thus, the unit 10 acquires the station 11 via a cell, that uses the same frequency as that which is allocated a code to each cell.

Abstract: PROBLEM TO BE SOLVED: To reduce the system cost by realizing switching capability of a large capacity in an optical asynchronous transfer mode ATM switching system so as to considerably decrease number of hardware sets. SOLUTION: A wavelength division multiplex/time division multiplex conversion module 24 demultiplexes an optical channel that is wavelength-multiplexed via a transmission link 23 of each input terminal of an optical ATM switch, converts the wavelength into a primary wavelength for path distribution for each channel, compresses cells to prevent collision among plural cells and applies time division multiplex processing to the cells. Then a 1st path distributor 25 distributes each cell whose wavelength is converted into the primary wavelength to a primary destination, a time division multiplex processing/wavelength division multiplex processing switching module 26 demultiplexes a channel signal distributed to a path, inversely compresses the signal into an original signal form, converts the wavelength into a wavelength to be distributed to a final destination, compresses the cells to prevent cell collision again and a 2nd path distributor 27 distributes the signal that is inversely compressed to the final destination.

Abstract: PROBLEM TO BE SOLVED: To reduce DC power consumption by using an on-board computer, so as to process a remote instruction sent from a ground to a satellite body. SOLUTION: When a system OS in a memory 330 is active normally, an on-board logic processor unit 310 after receiving a remote instruction from an instruction logic demodulator (CLD) 270 allows the memory 330 to generate a control signal and allows the memory 330 to store the instruction signal once received and gives the control signal to a SW programmable device 320 for authenticating the instruction and gives an authentication object instruction signal. Then the SW programmable device 320 uses a built-in instruction authentication software as a program, to generate an instruction authentication code and gives the instruction authentication code to the processor unit 310. Then the unit 310 selects a board of a transponder instruction electronic device 420, based on a selected address and gives a control signal to a power supply selection device 410, before transmitting data to the board.

Abstract: PROBLEM TO BE SOLVED: To provide a guide message of being out to a visitor, to store visitor's figure and voice in a storage medium and to reproduce later by controlling the output of the guide message of being out, compressively storing an inputted A/V signal and restoring and outputting this later. SOLUTION: If the visitor push a bell button 1 when being out, an HA controller 2 applies an automatic response control signal to an A/V controller 500 in an automatic response mode. The A/V controller 500 controls so as to read the guide message of being out previously stored in the storage medium 300, restore by an A/V decoder 400 and output it via a connecting part 100. Thus outputted guide message of being out is outputted to an external loudspeaker 6. Then, the HA controller 2 operates a camera 5 and a microphone 3 and controls so as to receive the A/V information of the visitor by its input and output via the connecting part 100. The A/V controller 500 compresses the A/V information of the visitor by an A/V encoder 200 and stores it in the storage medium 300.

Abstract: PROBLEM TO BE SOLVED: To attain simple coding at a high compression rate by splitting image data into blocks and applying compression coding to each block through the use of a BMI of each block. SOLUTION: Digital image data are divided into blocks each consisting of M1 ×M1 pixels, each block is discriminated as to whether each block is an edge block or other intermediate block and the intermediate block is compression-coded in the 1st process. In the 2nd process, each edge block is divided into blocks consisting of M2 ×M2 pixels which are smaller than the of M1 ×M1 pixels (M1 >M2 ), edge blocks and intermediate blocks are distinguished by the same method as the 1st process, a closest pattern is selected among M2 ×M2 pixel patterns prepared in advance in the case of edge blocks, its index, a size of BGV, and a mean value of edge block data are coded. In the 3rd process, intermediate blocks of the M2 ×M2 pixel blocks are compression-coded. Moreover, in the 4th process, a code to identify the intermediate block of the 1st block from the edge block of the 2nd block is added. The intermediate blocks in the 1st and 2nd processes are coded by using only their BMI.
