We propose two compressive multiplexers for the efficient sampling of ensembles of correlated signals. We show that we can acquire correlated ensembles, taking advantage of their (a priori-unknown) correlation structure, at a sub-Nyquist rate using simple modulation and filtering architectures. We recast the reconstruction of the ensemble as a low-rank matrix recovery problem from generalized linear measurements. Our theoretical results indicate that we can recover an ensemble of?M?correlated signals composed of?R \ll M?independent signals, each bandlimited to?W/2?Hz, by taking?O(RW log^q W)?samples per second, where?q > 1?is a small constant.
