Adaptive Kernel Kalman Filter
Mengwei Sun, Mike E. Davies, Ian K. Proudler +1
Sequential Bayesian filters in non-linear dynamic systems require the recursive estimation of the predictive and posterior distributions. This paper introduces a Bayesian filter ca…
Data provenance, curation and quality in metrology
James Cheney, Adriane Chapman, Joy Davidson +1
Data metrology -- the assessment of the quality of data -- particularly in scientific and industrial settings, has emerged as an important requirement for the UK National Physical…
OFDM-Based Optical Spatial Modulation
Anil Yesilkaya, Rui Bian, Iman Tavakkolnia +1
Spatial modulation (SM) has proven to be a promising multiple-input-multiple-output (MIMO) technique which provides high energy efficiency and reduces system complexity. In SM, onl…
Inexact Gradient Projection and Fast Data Driven Compressed Sensing
Mohammad Golbabaee, Mike E. Davies
We study convergence of the iterative projected gradient (IPG) algorithm for arbitrary (possibly nonconvex) sets and when both the gradient and projection oracles are computed appr…
Performance of Massive MIMO Uplink with Zero-Forcing receivers under Delayed Channels
Anastasios K. Papazafeiropoulos, Hien Quoc Ngo, Tharm Ratnarajah
In this paper, we analyze the performance of the uplink communication of massive multi-cell multiple-input multiple-output (MIMO) systems under the effects of pilot contamination a…
