Meeting the pressing power and bandwidth requirements of modern communication systems requires the development of highly efficient reconfigurable transceivers. On the receiver side, we present a new class of reconfigurable receiver that utilizes random projections to balance the power-bandwidth tradeoff. Such random projection front-ends are ubiquitous and allow the use of sub-Nyquist ADCs. These...
In this letter, we propose a new approach to reconfigurable receivers using random acquisition techniques. Random projections have been widely used within the context of compressive sensing for sub-Nyquist signal acquisition. In the system we propose, we design the random sensing signals so as to filter undesired components in the signal and result in measurements equivalent to those obtained had...
In this paper we propose a reconfigurable receiver that utilizes random demodulation, a compressive sensing architecture for efficient signal projection on a sensing signal. In the proposed system, the sensing signal is designed to annihilate the contribution of undesired frequency components in the collected measurements, thus allowing for the recovery of selected signal bands. The acquisition rate...
The theory of compressive sensing has recently been utilized to develop sub-Nyquist communication receivers that can reconstruct the input signal using sub-Nyquist sampling rates. Such samples are acquired randomly by projecting the input signal on random signals. Practically, these random signals can be generated by digital pseudo random signal generators, and the properties of these signals highly...
