摘要:
A method for providing increased sector-to-sector isolation when transmitting data between a plurality of Fourier transform matrices (105,110), each having an input Fourier transform matrix (FTM), an output FTM, and a plurality of transmit paths therebetween is disclosed. The method includes applying a tone to one of the plurality of transmit paths (410) so that a correlated output can be produced, measuring an output of the output FTM, correlating the output of the output FTM against the tone applied to produce a correlated output (320), adjusting a phase of the transmit path such that a direct current value of the correlated output is minimized, and adjusting an attenuation of the transmit path such that the direct current of the correlated output is minimized.

公开了一种在多个傅里叶变换矩阵(105,110)之间发送数据时提供增加的扇区到扇区隔离的方法,每个傅立叶变换矩阵具有输入傅立叶变换矩阵(FTM),输出FTM和它们之间的多个发送路径。 该方法包括:将多个发送路径(410)中的一个应用音调,使得可以产生相关输出,测量输出FTM的输出,将输出FTM的输出与所施加的音调相关联,以产生相关输出 (320),调整所述发送路径的相位使得所述相关输出的直流值最小化,以及调整所述发送路径的衰减,使得所述相关输出的直流电被最小化。
