Abstract： |
A method and equipment for decreasing the peak-mean power ratio in multi-carrier communication system is disclosed. Said method includes redistributing input signal power of power amplifier by digital value transform, determining the conversion point of numerical transform according to the probability distribution of input signal powers and determing the rule of numerical transform according to the requirement to input signal power of power amplifier at transmitter end, and reverse transform of receiver signals at receiver end. Its advantages are high effect, less calculations and less complexity. |
