| Abstract(in English) | A direct RF undersampling method is an important technique for simple circuits and devices because sampling frequency of Analogue-Digital converter (ADC) can be decreased. It is specially useful to measure spectrum in several wireless system at factory. We have proposed several methods to regenerate RF-spectrum by using direct undersampling data from parallel connected multi-ADCs. Some errors, which iare caused by different transmission functions of each path from common point to each ADCs, generate. This phenomena become obvious at higher frequency. A calibration method that the elements of connect matrix are transformed to each transfer function is proposed to suppress these errors in this report. We confirm an effectiveness of this method by a simulation. |
