<p><P>PROBLEM TO BE SOLVED: To realize variance compensation of data delay among reception-side panels in a W-CDMA base station device by a relatively small circuit scale. <P>SOLUTION: Delay amounts of transmission lines between a down transmission-side panel 101 and a plurality of down reception-side panels 102 are preliminarily measured by the plurality of down reception-side panels 102 respectively and are transmitted from respective down reception-side panels 102 to the down transmission-side panel 101, and synchronizing signals to be inputted to corresponding spreading units 104 in the down transmission-side panel 101 are controlled by a synchronizing signal control circuit 108 in accordance with the transmitted delay amounts, and spreading timings of spreading units 104 corresponding to respective down reception-side panels 102 are shifted to absorb the delay variance of down reception data among the plurality of down reception-side panels 102. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
