Robust massive MIMO Equilization for mmWave systems with low resolution ADCs
Leveraging the available millimeter wave spectrum will be important for 5G. In this work, we investigate the performance of digital beamforming with low resolution ADCs based on link level simulations including channel estimation, MIMO equalization and channel decoding. We consider the recently agreed 3GPP NR type 1 OFDM reference signals. The comparison shows sequential DCD outperforms MMSE-ba...
متن کاملSupervised-Learning-Aided Communication Framework for Massive MIMO Systems With Low-Resolution ADCs
This paper considers a massive multiple-inputmultiple-output (MIMO) system with low-resolution analog-todigital converters (ADCs). In this system, inspired by supervised learning, we propose a novel communication framework that consists of channel training and data detection. The underlying idea of the proposed framework is to use the input-output relations of a nonlinear system, formed by a ch...
متن کاملUplink Multiuser Massive MIMO Systems with Low-Resolution ADCs: A Coding-Theoretic Approach
This paper considers an uplink multiuser massive multiple-input multiple-output (MIMO) system with lowresolution analog-to-digital converters (ADCs), in which K users with a single-antenna communicate with one base station (BS) with Nr antennas. In this system, we present a novel multiuser MIMO detection framework that is inspired by coding theory. The key idea of the proposed framework is to c...
متن کاملOn Low-Resolution ADCs in Practical 5G Millimeter-Wave Massive MIMO Systems
Nowadays, millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems is a favorable candidate for the fifth generation (5G) cellular systems. However, a key challenge is the high power consumption imposed by its numerous radio frequency (RF) chains, which may be mitigated by opting for low-resolution analog-to-digital converters (ADCs), whilst tolerating a moderate performan...
متن کاملThroughput analysis of massive MIMO uplink with one-bit ADCs
Massive MIMO is a disruptive technology that consists of equipping communication transceivers with an excessive number of antennas to enable unprecedented gains in throughput and radiated energy efficiency. From an industry perspective, massive MIMO will happen only if the required large antenna arrays can be built out of low-cost (and, hence, low-precision) components. Therefore it is of inter...
