<p><P>PROBLEM TO BE SOLVED: To detect an accurate receiving quality by a radio transmission system such as a HSDPA system or the like. <P>SOLUTION: The receiving quality of a signal transmitted by a code division multiple access system is determined. When the receiving quality is determined by a system having a synchronous channel which does not have an orthogonal relation with a channel to receive a data, a noise component of a desired channel is determined, a degree of the noise component originated in the synchronous channel to the determined noise is determined, and the receiving quality of the receiving channel is detected on the basis of the degree of the determined noise component. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
