<p><P>PROBLEM TO BE SOLVED: To provide a novel amplitude limit state monitoring means capable of ensuring transmission of a signal with high quality on the basis of multiplexed user data assigned from a user data control section. <P>SOLUTION: A plurality of the user data (11a to 11n) assigned by the user data control section 1 are subjected to coding processing by mutualy different codes in spread sections 31 to 3n, a summing composite section 4 multiplexes the resulting data, and an amplitude limit section 5 applies peak clip processing to the multiplexed data and outputs the resulting data to a wireless transmission section 6. A comparison calculation circuit section 7 compares the average power of the multiplexed data before amplitude limit by the amplitude limit section 4 and each average power of the multiplexed data after the amplitude limit is supervised for a prescribed period, and the user data control section 1 controls the assignment of the user data to a transmission reception section 21 in response to an average gain difference between the both. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
