发明名称 OUTPUT POWER ERROR ABSORBING CIRCUIT AND MULTI-CARRIER TRANSMITTER HAVING THE SAME
摘要 <P>PROBLEM TO BE SOLVED: To constantly obtain transmission (output) power to be desired even when the number of carriers and carrier frequency allocation are different in equipment for suppressing a peak corresponding to input limit power of a power amplifier. <P>SOLUTION: The output power error absorbing circuit is provided with a power correction value generator 40, which calculates a power correction value for minimizing an error in-between a reference output power value of a carrier multiplexed signal caused by peak power suppression under carrier settings, on the basis of the carrier settings and peak suppression settings regarding either of or both of the number of carrier signals and the frequency allocation; and an output power error correcting part 46 which corrects a signal gain before or after multiplexing the carrier signals, by using the power correction value obtained by the power correction value generating part 40. <P>COPYRIGHT: (C)2006,JPO&NCIPI
