Interference Exploitation Precoding for Multi-Level Modulations: Closed-Form Solutions
Ang Li, Christos Masouros, Yonghui Li +2
In this paper, we study closed-form interference-exploitation precoding for multi-level modulations in the downlink of multi-user multiple-input single-output (MU-MISO) systems. We…
1-Bit Massive MIMO Downlink Based on Constructive Interference
Ang Li, Christos Masouros, A. Lee Swindlehurst
In this paper, we focus on the multiuser massive multiple-input single-output (MISO) downlink with low-cost 1-bit digital-to-analog converters (DACs) for PSK modulation, and propos…
Reconsidering Linear Transmit Signal Processing in 1-Bit Quantized Multi-User MISO Systems
Oliver De Candido, Hela Jedda, Amine Mezghani +2
In this contribution, we investigate a coarsely quantized Multi-User (MU)-Multiple Input Single Output (MISO) downlink communication system, where we assume 1-Bit Digital-to-Analog…
Spectral Efficiency of Mixed-ADC Massive MIMO
Hessam Pirzadeh, A. Lee Swindlehurst
We study the spectral efficiency (SE) of a mixed-ADC massive MIMO system in which K single-antenna users communicate with a base station (BS) equipped with M antennas connected to…
Quantized Constant Envelope Precoding with PSK and QAM Signaling
Hela Jedda, Amine Mezghani, A. Lee Swindlehurst +1
Coarsely quantized massive Multiple-Input Multiple-Output (MIMO) systems are gaining more interest due to their power efficiency. We present a new precoding technique to mitigate t…
