A greedy algorithm for pilot contamination mitigation using LAP
Journal of Engineering and Applied Science, 2023 In this paper, we propose a linear assignment problem (LAP) scheme using greedy algorithms to alleviate the intercell interference (ICI) in massive multi-input multiple-output (maMIMO) systems.

A massive MIMO system based multi-length pilot scheme
上海师范大学学报. 自然科学版, 2016 In massive MIMO system,pilot contamination is considered as a challenging problem,which deteriorates channel estimation at base station (BS) and therefore reduces the total throughput.In the conventional single-length pilot schemes,such contamination is ...

Pilot Decontamination Using Asynchronous Fractional Pilot Scheduling in Massive MIMO Systems
Sensors, 2020 Due to large spectral efficiency and low power consumption, the Massive Multiple-Input-Multiple-Output (MIMO) became a promising technology for the 5G system. However, pilot contamination (PC) limits the performance of massive MIMO systems.

Pilot contamination reduction in massive MIMO systems based on pilot scheduling [PDF]
EURASIP Journal on Wireless Communications and Networking, 2018 Abstract The pilot contamination caused by sharing the non-orthogonal pilots among users is considered to be a bottleneck of the massive multi-input multi-output (MIMO) systems. This paper proposes a pilot scheduling scheme based on the degradation to address this problem.

MAX-SLNR Precoding Algorithm for Massive MIMO System
MATEC Web of Conferences, 2016 Pilot Contamination obviously degrades the system performance of Massive MIMO systems. In this paper, a downlink precoding algorithm based on the Signal-to- Leakage-plus-Noise-Ratio (SLNR) criterion is put forward.
