Abstract: PROBLEM TO BE SOLVED: To provide web site directory service information for dial call access. SOLUTION: A web site includes various functions accessible in the web site of the Internet, that is, service web site directory information. The web site directory information indicates an indexed database displayed as a menu item on a display device of a remote unit, that is, a mobile unit (called a remote control transceiver) in a wireless, that is, cellular electric communication system. For example, the web access information for the service categorized from category information such as stocks, movie and office mail information (mail provider) and maintained in the indexed database is a URL, a switch channel network dial call access number or other web site source identifier.

Abstract: PROBLEM TO BE SOLVED: To provide an efficient sharing of a hardware processing stage in processing samples from a plurality of independent input sequences that are grouped prior to application to the processing arrangement by an efficient hardware architecture and processing method. SOLUTION: By applying a signal sequence Yi: j=0, 1, 2,..., MN-1} obtained by interleaving M-sets of signal sequences Xi,j: J-0, 1, 2,..., N-1; i=1, 2,..., M}, a sophisticated processing engine efficiency and/or reduction in the delay to receive the new input sample is achieved. Thus, the processing of the sample Yj is immediately started when the processing of the sample Yj-M is finished. Accordingly, a pipeline stage delay Dp can efficiently by reduced to 1/M (from Dmax to Dmax/M) and the number (or an equivalently required time) of required engines can similarly be reduced to 1/M).

Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber transmitting link, with which channel destruction caused by stimulated Raman scattering is reduced. SOLUTION: An optical fiber transmitting link 20, with which the channel destruction caused by stimulated Raman scattering is reduced, is formed by providing a high-pass optical filter 22 inside a transmitting fiber. The filter is provided with one or plural other components sometimes and is formed as a filter 'distributed' along the length of the optical fiber as well. A cutoff frequency concerning the high-pass optical filter is selected just below the frequency of an input channel to be transmitted. When using the link inside configuration accompanied with a large number of input channels, the cutoff frequency is controlled to be just below the lowest input channel frequency.

Abstract: PROBLEM TO BE SOLVED: To provide a method for reconfiguring a communication system, in order to effect high quality communication. SOLUTION: In the communication system of the present invention, a transmitter is reconfigured based on the state of a mobile station, e.g. the functions and capacity of a mobile station receiver, the ratio of carrier vs interference waves or the signal/noise ratio and the mobility of the mobile station. Consequently, the arrangement of the transmitter is optimized to the state of a specific mobile station receiver. In one embodiment, the transmitter is selected to operate in single transmit antenna configuration, a space time configuration, selective transmit diversity configuration or multi-output multi-input configuration.

Abstract: PROBLEM TO BE SOLVED: To provide uplink traffic channel allocation using an exclusive control channel capable of ensuring the designated parts of a control channel resource for transferring uplink traffic channel requests. SOLUTION: A response to an uplink traffic channel request 1 transmitted from a traveling object device 202-1 in a group G1 is transmitted from a base station 201 between time slots S2 and S3, and received between time slots S4 and S5. The traveling object device 201-1 retransmits an uplink traffic channel request 1 in a group G2 without waiting for this response from the base station 201. Next, the traveling object device 202-1 receives the response from the base station 201. Then, the traveling object device 202-1 is able to transmit an uplink traffic channel request 2 in a group 3.

Abstract: PROBLEM TO BE SOLVED: To provide an adaptive antenna array technique to be used in an orthogonal frequency division multiplex spread spectrum multiple access(OFDM- SSMA) cellular wireless system. SOLUTION: A base station receiver is mounted with an adaptive antenna gain algorithm 126 for estimating a space covariance matrix related with each mobile station. The space covariance matrix in one base station is decided based on the hopping sequence of the mobile stations, and correlation between the signals received from the mobiles stations is provided by different antenna elements 114 in an antenna array. The estimated value of an interference matrix is generated concerning K pieces of mobile stations from the individual space covariance matrixes and the mean space covariance matrix, and array responses related with the respective mobile stations are generated from the estimated value of the interference matrix. Then, antenna weighting is decided from the array response related with the prescribed mobile station, and the antenna weighting is applied to the signal received form the prescribed mobile station.

Abstract: PROBLEM TO BE SOLVED: To provide a spatiotemporal processor corresponding to a radio system equipped with a plurality of transmission and reception antennas, in which even when the correlation of a certain level to be used in a multi-input multi-output(MIMO) system exists, it is possible to develop (generate) signals capable of achieving the maximum open loop capacity by channels having the correlation of the level, since the signals have the correlation of a certain level, and performance deterioration and the capacity reduction is generated when the correlation of those signals is ignored. SOLUTION: Even when the correlation of a certain level to be used in a radio system having a plurality of transmission antennas and reception antennas exists, it is possible to develop (generate) signals capable of achieving the maximum open loop capacity by channels having the correlation. In this principle, signals to be transmitted by various antennas are processed so that the maximum information carrying capabilities can be improved. That is, data to be transmitted are divided into (M+1) pieces of sub-streams. One connected signal constituted of one common weighted version of the sub-streams and one corresponding weighted version to be frequently supplied to the antennas of the sub-streams is supplied to the respective transmission antennas, and M pieces of transmission signals are allowed to exist as a whole. A receiver equipped with N pieces of antennas receive the M pieces of transmission signals connected by the channels, and reconstitute the original data from those transmission signals. This is achieved by using a series of decoding processes.

Abstract: PROBLEM TO BE SOLVED: To provide an antenna system in which a traffic load is distributed uniformly between cells or between sectors of the cells by a method wherein, even when each cell is loaded heavily, a radio call can be established and processed and, when a traffic is overloaded, a soft hand-off operation to another base station inside an adjacent cell can be performed. SOLUTION: Antenna components for a cylindrical antenna array is adjusted, and a load is dynamically shared among the sectors of the cells or among the cells. The antenna component adjusts a beam arrangement or a beam direction on the basis of the monitored load. Consequently, the coverage region of the antenna array is changed so as to cope with a change in the density of the traffic. The antenna component is adjusted, and a change in the load inside each cell or between the cells is housed.
