Title:
信号測定方法
Document Type and Number:
Japanese Patent JP6910791
Kind Code:
B2
Abstract:
Embodiments of the present invention provide techniques and methods for improving signal-to-noise ratio (SNR) when averaging two or more data signals by finding a group delay between the signals and using it to calculate an averaged result. In one embodiment, a direct average of the signals is computed (305) and phases are found for the direct average and each of the data signals 310 and 315). Phase differences are found between each signal and the direct average (320). The phase differences are then used to compensate the signals (335).
