Abstract: front page image
(EN)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 signal to be modulated is treated as the signal to be modulated for each corresponding baseband signal. 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.
(FR)La présente invention concerne un procédé permettant de réduire les interférences mutuelles multi-porteuses, qui comprend : une phase d'au moins un signal à moduler est ajustée; chaque signal de bande de base est modulé sur chaque signal à moduler respectivement; les indicateurs de performances inter-signal après modulation sont comparés aux indicateurs de performances prédéfinis et, si les indicateurs de performances prédéfinis ne peuvent pas être atteints, la phase d'au moins un signal à moduler parmi les signaux à moduler est ajustée jusqu'à ce que les indicateurs de performances inter-signal atteignent les indicateurs de performances prédéfinis; lorsque les indicateurs de performances prédéfinis sont atteints, chaque signal actuel à moduler est considéré comme le signal à moduler pour chaque signal de bande de base correspondant. L'invention concerne également, entre-temps, un dispositif permettant de réduire les interférences mutuelles multi-porteuses. À condition de configurer de façon adjacente les multiples porteuses, l'amélioration des performances autorisée par l'invention est particulièrement évidente et il est possible de faire travailler simultanément de multiples porteuses dans une même zone de couverture de signal sans fil; en outre, l'efficacité d'utilisation du spectre de fréquence est considérablement améliorée.
(ZH)本发明公开了一种降低多载波相互干扰的方法,包括:调整至少一个被调信号的相位;将各基带信号分别调制在各被调信号上;将调制后信号间的性能指标与设定的性能指标进行比较,不能满足设定性能指标时,调整被调信号中至少一个被调信号的相位,直到信号间的性能指标满足设定性能指标;满足设定性能指标时,将当前的各被调信号作为各对应基带信号的被调信号。本发明同时公开了一种降低多载波相互干扰的装置。本发明在多载波相邻配置情况下对性能的改善尤为明显,并使得同一个无线信号覆盖区域可以有多载波同时工作,大大提高了频谱利用率。
