Abstract: 本发明公开了一种降低多载波相互干扰的方法，包括：调整调制信号的延迟；将调整后的调制信号调制到被调信号上；将调制后信号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，继续调整所述调制信号的延迟，满足设定性能指标时，将当前的调制信号作为输入信号；或将当前的调制后信号作为输出信号。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。

Abstract: The disclosure discloses a method for reducing mutual interference of multi-carrier, comprising: adjusting the delay of at least one modulation signal; respectively modulating each adjusted modulation signal onto each modulated signal; and comparing the performance indices of modulated signals with set performance indices, wherein the delay of at least one modulation signal is adjusted when the set performance indices are not reached, until the performance indices of modulated signals reach the set performance indices, and each current modulated signal is set as an output signal, or each current modulation signal is set as an input signal when the set performance indices are reached. The disclosure further discloses an apparatus for reducing mutual interface of multi-carrier. The disclosure can improve the performance obviously under the circumstance of arranging the multi-carrier adjacent to each other, and enable the multiple carriers to operate simultaneously in the coverage area of one radio signal, thereby greatly improving the frequency spectrum utilization ratio.

Abstract: The present invention provides systems and methods for parallel interference suppression. In one embodiment of the invention, a processing engine is used to substantially cancel a plurality of interfering signals within a received signal. The processing engine includes a plurality of matrix generators that are used to generate matrices, each matrix comprising elements of a unique interfering signal selected for cancellation. The processing engine also includes one or more processors that use the matrices to generate cancellation operators. A plurality of applicators applies the cancellation operators to parallel but not necessarily unique input signals to substantially cancel the interfering signals from the input signals. These input signals may include received signals, interference cancelled signals and/or PN codes.
