METHOD AND DEVICE FOR DECREASING MULTI-CARRIER MUTUAL INTERFERENCE

摘要

A method for decreasing multi-carrier mutual interference is disclosed, which includes that: a phase of at least one signal to be modulated is adjusted; each baseband signal is modulated onto each signal to be modulated respectively; the inter-signal performance indicators after modulation are compared with preset performance indicators, and if the preset performance indicators cannot be met, the phase of at least one signal to be modulated among the signals to be modulated is adjusted until that the inter-signal performance indicators meet the preset performance indicators; when the preset performance indicators are met, each current phase value is accepted as the phase value of each signal to be modulated. Meanwhile, a device for decreasing the multi-carrier mutual interference is disclosed in the invention. Under the condition that the multiple carriers are configured adjacently, the performance improvement by the present invention is especially obvious, 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.
