METHOD AND APPARATUS FOR REDUCING MUTUAL INTERFERENCE OF MULTI-CARRIER

摘要

A method for reducing mutual interference of multi-carrier includes that: the delay of at least one modulation signal is adjusted; each adjusted modulation signal is separately modulated onto each signal to be modulated; the performance indices of modulated signals are compared with set performance indices, the delay of at least one modulation signal is adjusted when the set performance indices can not be met, until the performance indices of modulated signals meet the set performance indices; when the set performance indices are met, each current modulated signal is set as an output signal, or each current modulation signal is set as an input signal. The present invention also discloses an apparatus for reducing mutual interference of multi-carrier. The present invention can improve the performance obviously under the circumstance of arranging the multi-carrier adjacent to each other, and makes the multi-carrier be operated simultaneously in the same radio signal coverage area, therefore greatly improving the frequency spectrum utilization ratio.
