One-Bit Sphere Decoding for Uplink Massive MIMO Systems with One-Bit ADCs
Yo-Seb Jeon, Namyoon Lee, Song-Nam Hong +1
This paper presents a low-complexity near-maximum-likelihood-detection (near-MLD) algorithm called one-bit-sphere-decoding for an uplink massive multiple-input multiple-output (MIM…
Feedback Design for Multi-Antenna K-tier Heterogeneous Downlink Cellular Networks
Jeonghun Park, Namyoon Lee, Robert W. Heath
We characterize the ergodic spectral efficiency of a non-cooperative and a cooperative type of K-tier heterogeneous networks with limited feedback. In the non-cooperative case, a m…
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…
Uplink Multiuser Massive MIMO Systems with Low-Resolution ADCs: A Coding-Theoretic Approach
Song-Nam Hong, Seonho Kim, Namyoon Lee
This paper considers an uplink multiuser massive multiple-input-multiple-output (MIMO) system with low-resolution analog-to-digital converters (ADCs), in which K users with a singl…
Degrees of Freedom and Achievable Rate of Wide-Band Multi-cell Multiple Access Channels With No CSIT
Yo-Seb Jeon, Namyoon Lee, Ravi Tandon
This paper considers a -cell multiple access channel with inter-symbol interference. The primary finding of this paper is that, without instantaneous channel state information a…
Uplink Multiuser Massive MIMO Systems with One-Bit ADCs: A Coding-Theoretic Viewpoint
Seonho Kim, Namyoon Lee, Songnam Hong
This paper investigates an uplink multiuser massive multiple-input multiple-output (MIMO) system with one-bit analog-to-digital converters (ADCs), in which users with a single-…
