Optimal Joint Channel Estimation and Data Detection by L1-norm PCA for Streetscape IoT

George Sklivanitis, Konstantinos Tountas, Nicholas Tsagkarakis, Dimitris A. Pados, Stella N. Batalama
ICASSP 2020accepted

We prove, for the first time in the literature of communication theory and machine learning, the equivalence of joint maximum-likelihood (ML) optimal channel estimation and data detection (JOCEDD) to the problem of finding the L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http:/…

Small-Sample-Support Channel Estimation for Massive Mimo Systems

George Sklivanitis, Konstantinos Tountas, Dimitris A. Pados, Stella N. Batalama
ICASSP 2018accepted

We consider the problem of blind channel estimation with minimal pilot signaling in multi-cell multi-user MIMO systems with very large antenna arrays at the base station. We develop a least-squares (LS)-type algorithm that iteratively extracts channel and data estimates in short-data record multicel…

Sparse waveform design for all-spectrum channelization

George Sklivanitis, Panos P. Markopoulos, Stella N. Batalama, Dimitris A. Pados
ICASSP 2017accepted

We introduce maximum-SINR sparse-binary waveforms that modulate data information symbols from any finite alphabet and span the whole continuum of the available/device-accessible spectrum. We offer an optimal algorithm that designs the proposed waveforms by maximizing the signal-to-interference-plus-…
