Co-prime arrays can estimate the directions of arrival (DOAs) of O ( M N ) sources with O ( M + N ) sensors, and are convenient to analyze due to their closed-form expression for the locations of virtual lags. However, the number of degrees of freedom is limited due to the existence of holes in difference coarrays if subspace-based algorithms such as the(More)
A novel and efficient Sub-Nyquist architecture for multi-channel compressive sensing based on compressive multiplexer (CMUX) and modulated wideband converter (MWC) is proposed with the name of CM-MWC. Each channel in this multi-channel receiver system is mixed down to baseband, and then randomly modulated by a periodical pseudo-random sequence. The randomly(More)
