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

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:/…

Dynamic Joint PHY-MAC Waveform Design for IoT Connectivity

ICASSP 2019accepted

We envision dense network deployments of Internet-of-Things (IoT) connected devices that report data to a common base station (BS). The devices utilize repeats of a basic shaping pulse occupying the entire continuum of the device-accessible spectrum. We propose an optimal algorithm to adaptively des…

Small-Sample-Support Channel Estimation for Massive Mimo Systems

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…
