Group-Blind Detection with Very Large Antenna Arrays in the Presence of Pilot Contamination


Massive MIMO is, in general, severely affected by pilot contamination. As opposed to traditional detectors, we propose a group-blind detector that takes into account the presence of pilot contamination. While sticking to the traditional structure of the training phase, where orthogonal pilot sequences are reused, we use the excess antennas at each base station to partially remove interference during the uplink data transmission phase. We analytically derive the asymptotic SINR achievable with group-blind detection, and confirm our findings by simulations.

ON PILOT-SYMBOL AIDED CHANNEL ESTIMATION IN FBMC-OQAM


Filter Bank Multi-Carrier (FBMC) modulation is considered as a possible candidate for 5G. Compared to OFDM, channel estimation becomes more challenging in FBMC due to the imaginary interference, which has to be canceled at the pilot positions either by auxiliary pilot symbols or coding.

Detection of False Data Injection Attacks in Smart Grid Communication Systems


The transformation of traditional energy networks to smart grids can assist in revolutionizing the energy industry in terms of reliability, performance and manageability. However, increased connectivity of power grid assets for bidirectional communications presents severe security vulnerabilities. In this paper, we investigate Chi-square detector and cosine similarity matching approaches for attack detection in smart grids where Kalman filter estimation is used to measure any deviation from actual measurements.

Likelihood-Based Modulation Classification for MU-MIMO Systems


MU-MIMO System Model

The problem of optimal likelihood based modulation classification (MC) for optimal detection in 2x2 multiuser MIMO (MU-MIMO) receivers is considered. The optimal Log-MAP classifier is computationally exhaustive, and its sub-optimal Max-Log-MAP version poses remarkable degradation in performance. Between these two extremes, we propose four computationally simplified methods for MC, by taking special subsets of Euclidean distance computations that constitute the decision metric.

Low-Complexity MIMO Detector with 1024-QAM


1024QAM and Beyond

In this paper, dual layer multiple-input multiple-output (2x2 MIMO) systems that use the 1024-QAM modulation are studied. We build on the layered orthogonal lattice detector (LORD), which achieves optimal maximum-likelihood (ML) performance, but which has high complexity with 1024-QAM, and argue that the low-complexity version of LORD (LC-LORD) introduces a significant performance degradation, especially with high channel correlation. We propose several approaches that outperform LC-LORD at a lower complexity.
