摘要： In a wireless access system which uses the sector antenna of a radio base station to transmit an access channel to and receive an access channel from a radio terminal in each frame, and which switches the sector at each frame, the sector ID s is set in a specific functional relation to the access channel ID a, and a radio terminal which communicates with a radio base station transmits and receives in accordance with the access channel ID a without knowing the sector ID s.

摘要： A method for producing a packed article of a plurality of box-like packages having the same dimension is provided. The method comprising the steps of: forming a first layer of packages by arranging a plurality of box-like packages in a predetermined pattern; forming upper layers of packages, each upper layers including the same number of the packages as that of said first package and having the same pattern as that of said first layer; forming an intermediate layer of packages, said intermediate layer including number of packages less than that of said first layer or said upper layers; and disposing said intermediate layer between said first layer and the upper layer adjacent to said first layer so as to form spaces on opposite sides of said intermediate layer.

摘要： An OFDM signal communication system used in broadband mobile communication, achieves stable operation under severe frequency selective fading environments, giving high quality. The OFDM signal communication system which transmits OFDM signals over the same radio frequency from N transmitting antennas, has an inverse matrix computer for computing an N×N inverse matrix constituted by propagation coefficients for respective propagation paths between each of N transmitting antennas and each of N receiving antennas, and a subcarrier demodulator which separates the signals of the respective propagation paths, based on the obtained inverse matrix.
