In this paper, we propose iterative interference cancellation schemes with access points selection (APs-Sel) for cell-free massive multiple-input multiple-output (CF-mMIMO) systems. Closed-form expressions for centralized and decentralized linear min

Systems with 1-bit quantization and oversampling are promising for the Internet of Things (IoT) networks because they can reduce the power consumption of the analog-to-digital-converters in the devices. The novel time-instance zero-crossing (TI ZX) m

Abstract A channel with continuous phase modulation and 1-bit ADC with oversampling is considered. Due to oversampling, higher-order modulations yield a higher achievable rate and this study presents methods to approach this with sophisticated channe

Large-scale multiple-antenna systems with large bandwidth are fundamental for future wireless communications, where the base station employs a large antenna array. In this scenario, one problem faced is the large energy consumption as the number of r

Abstract Receivers based on 1-bit quantization and oversampling with respect to the transmit signal bandwidth enable a lower power consumption and a reduced circuit complexity compared to conventional amplitude quantization. In this work, the achieva

In this work, large-scale multiple-antenna systems are investigated, where the base station employs a large antenna array with low-cost and low-power 1-bit analog-to-digital converters. To compensate for the performance loss caused by the coarse quan

The classic line-of-sight (LoS) MIMO systems optimize antenna spacings according to the communication distance, and the subchannels of fixed symmetric arrays are sensitive with distance variations. Under array aperture constraints, this letter shows
