<P>PROBLEM TO BE SOLVED: To provide a multicarrier transmission system and receiving apparatus for multicarrier transmission capable of controlling a method of despreading a pilot channel while considering the state of a transmission line in multicarrier transmission. <P>SOLUTION: A reception apparatus 40 which receives a multicarrier CDMA signal from a transmission apparatus 20, despreads a pilot symbol in a pilot channel despreading section 44. A parameter control section 48 succeeds a result of despreading from the pilot channel despreading section 44 and estimates a despreading rate of a pilot channel which is orthogonal with another multiplexed channel group. The parameter control section 48 estimates a transmission line and calculates a delay spread. The derived despreading rate and delay spread of the pilot channel are then used to determine the pilot channel despreading rate while referring to a despreading method determination table. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
