Low-Complexity Symbol-Level Precoding for MU-MISO Downlink Systems with QAM Signals
Sungyeal Park, Yunseong Cho, Songnam Hong
This study proposes the construction of a transmit signal for large-scale antenna systems with cost-effective 1-bit digital-to-analog converters in the downlink. Under quadrature-a…
Quantized Massive MIMO Systems with Multicell Coordinated Beamforming and Power Control
Jinseok Choi, Yunseong Cho, Brian L. Evans
In this paper, we investigate a coordinated multipoint (CoMP) beamforming and power control problem for base stations (BSs) with a massive number of antenna arrays under coarse qua…
Coordinated Multicell Beamforming and Power Allocation for Massive MIMO with Low-Resolution ADC/DAC
Yunseong Cho, Jinseok Choi, Brian L. Evans
In this work, we present a solution for coordinated beamforming and power allocation when base stations employ a massive number of antennas equipped with low-resolution analog-to-d…
Construction of 1-Bit Transmit Signal Vectors for Downlink MU-MISO Systems: QAM constellations
Sungyeal Park, Yunseong Cho, Songnam Hong
In this paper, we investigate the construction of a transmit signal for a base station with a massive number of antenna arrays under the cost-effective 1-bit digital-to-analog conv…
Robust Learning-Based ML Detection for Massive MIMO Systems with One-Bit Quantized Signals
Jinseok Choi, Yunseong Cho, Brian L. Evans +1
In this paper, we investigate learning-based maximum likelihood (ML) detection for uplink massive multiple-input and multiple-output (MIMO) systems with one-bit analog-to-digital c…
Successive Cancellation Soft Output Detector For Uplink MU-MIMO Systems With One-bit ADCs
Yun-Seong Cho, Seonho Kim, Song-Nam Hong
In this paper, we present a successive-cancellation-soft-output (SCSO) detector for an uplink multiuser multiple-input-multiple-output (MU-MIMO) system with one-bit analog-to-digit…
