The analog to information converter (AIC) based on compressed sensing (CS) is designed to sample the analog signals at a sub-Nyquist sampling rate. In this paper, we propose a novel parallel multi-rate compressed sampling (PMCS) system. It has several parallel paths and each path has several low-speed analog-to-digital converters (ADCs). This system has simple structure and low sampling rate, which makes it easy to be implemented on hardware. Simulation results show that signals can be reconstructed in high probability even though the sampling rate is much lower than the Nyquist sampling rate.
