This article presents the architecture of a reconfigurable radio receiver intended for multistandard applications. The receiver is based on RF sampling and discrete time analog signal processing. Anti-alias filtering, downconversion by bandpass sampling, channel selection filtering and sampling rate decimation are performed throughout the receiver chain. By adjusting the input sampling rate, all these operations can be tuned to different RF bands. This achieves full system reconfigurability and allows us to cover most of the existing communication standards.
