Compressive sensing (CS) has recently become a critical technique to reduce the high computational cost of signal processing systems. One of the main signal processing modules of CS systems is the signal reconstruction processor. Orthogonal matching pursuit (OMP) is one of the main signal reconstruction algorithms because of its low complexity and high regularity compared with the greedy $l1$ algorithm...
In the next-generation 5G system, millimeter wave (mmWave) multiple-input multiple-output (MIMO) system utilizes massive antennas at transmitter and receiver to increase the throughput and reliability. Due to the short wavelength of mmWave signals, more antennas can be adopted to alleviate severe channel path loss. However, the increase of RF chains raises the chip cost of the transceiver. Thus, hybrid...
