Multi-channel random demodulation for hardware efficient compressive sensing

In this paper we propose and analyze the multichannel random demodulator, a compressive sensing system employing multiple random demodulation channels. This system fills the gap between a single channel system, the random demodulator, and an M channel system, which acquires one measurement per channel. The trade-off for changing the number of channels involves hardware efficiency and compactness. We provide an analysis of this trade-off and study the performance of the multi-channel random demodulator.
