<P>PROBLEM TO BE SOLVED: To solve the problem of the conventional art that all signals of all carriers cannot be used since the conventional art fails to adopt a configuration in which channel estimation is performed using a plurality of known signals so as to perform channel equalization and decryption of a desired signal. <P>SOLUTION: The invention includes: a channel estimation section 204 for deriving n types of channel estimation values for n types of ideal signals for first signals for the first signals received for every M number of carriers; a channel equalization section 205 for carrying out n types of channel equalizations by using the n types of channel estimation values derived by the channel estimation section 204 from the first signals for second signals received for each of M number of carriers; and a scramble code decryption section 206 for carrying out evaluation for n types of ideal signals for the second signal for each of n types of scramble codes for the second signals after equalization of (N×M) number of channel equalizations for n types for each of M number of carriers and carrying out decryption of the scramble code with evaluation result matching the conditions set beforehand among the n types of scramble codes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
