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…
Greedy Sparse Signal Recovery Algorithm Based on Bit-wise MAP detection
J. Chae, S. -N. Hong
We propose a novel greedy algorithm for the support recovery of a sparse signal from a small number of noisy measurements. In the proposed method, a new support index is identified…
Supervised-Learning for Multi-Hop MU-MIMO Communications with One-Bit Transceivers
Daeun Kim, Song-Nam Hong, Namyoon Lee
This paper considers a nonlinear multi-hop multi-user multiple-input multiple-output (MU-MIMO) relay channel, in which multiple users send information symbols to a multi-antenna ba…
Semi-Supervised Learning Detector for MU-MIMO Systems with One-bit ADCs
Seonho Kim, Song-Nam Hong
We study an uplink multiuser multiple-input multiple-output (MU-MIMO) system with one-bit analog-to-digital converters (ADCs). For such system, a supervised-learning (SL) detector…
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…
A Low-Complexity Soft-Output wMD Decoding for Uplink MIMO Systems with One-Bit ADCs
S. Kim, N. Lee, S. -N. Hong
This paper considers an uplink multiuser multiple-input-multiple-output (MU-MIMO) system with one-bit analog-to-digital converters (ADCs), in which users with a single transmit…
