METHOD AND DEVICE FOR REDUCING MUTUAL INTERFERENCE FOR MULTI-CARRIER

摘要

A method for reducing mutual interference for multi-carrier includes: adjusting the phase of at least one signal to be modulated; modulating each baseband signal onto each signal to be modulated respectively; judging whether each baseband signal can be demodulated correctly, when the baseband signals which can not be correctly demodulated exist, adjusting the phase of at least one signal to be modulated of the signals to be modulated, until all the baseband signals can be demodulated correctly; when all can be demodulated correctly, accepting the current phase value as the phase value of the signal to be modulated of each baseband signal. Meanwhile, a device for reducing mutual interference for multi-carrier is provided. The performance improvement by the present invention is especially obvious in the case of adjacent configuring for multi-carrier, and it is made possible that there are multiple carriers working simultaneously within a same wireless signal coverage area, and the frequency spectrum utilization efficiency is greatly increased.
