| Abstract(in English) | A Direct RF undersampling method is an important technique for simple circuits and devices because sampling frequency of Analogue to Digital converter 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. Sampling numbers of each ADCs are important parameters in order to regenerate RF spectrum. We show a relation between independent variables of these sampling number and some band conditions. These sampling numbers are conventionally set to relatively primes to keep independent variables. Therefore, independent variables can not be kept because of the prime number restriction when high speed signal processing is necessary. We show there is a suitable condition at the case of not relatively primes in this report. |
