Abstract
A method of direct RF digitization for multiple RF signal bands such GNSS or wireless communication signal bands and a receiver using the method. By using the method, an optimal sampling frequency to be used in direct RF digitization for signals of multiple RF signal bands can be easily obtained. According to the present invention, one or more of the RF signal bands are selected to be shifted to target band(s). By doing so, the optimal sampling frequency can be easily calculated. Then the obtained sampling frequency is used in executing the direct RF digitization.
