<p><P>PROBLEM TO BE SOLVED: To improve the stability of communication in a repeater which is used for wireless communication of a code-division multiple-access system. <P>SOLUTION: The repeater is provided with: an antenna 21 for a base-station; two antennas 22-1 and 22-2 for two mobile stations each of which forms antenna patterns of different directivity; repeating means (master-station side device 30 and slave-station side devices 40-1 and 40-2) of relaying and outputting a signal received from the antenna 21 for the base station as a transmitted signal from the antennas 22-1 and 22-2 for the mobile stations to a mobile station having a rake receiving function; and a delay device 36 which gives a delay time of more than one chip of a spread signal of the code-division multiple-access system between transmitted signals outputted with adjacent antenna patterns of the antennas 22-1 and 22-2 for the mobile stations. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
