Channel Estimation for Millimeter Wave Massive MIMO Systems Using Separable Compressive Sensing
IEEE Access, 2021 Channel estimation is a fundamental problem for downlink transmission in millimeter wave (mmWave) multiple input multiple output (MIMO) systems. This paper proposes a channel estimation algorithm by exploiting the separable structured sparsity of mmWave ...

The Extended-Window Channel Estimator for Iterative Channel-and-Symbol Estimation
EURASIP Journal on Wireless Communications and Networking, 2005 L'application de l'algorithme de maximisation des attentes (EM) à l'estimation des canaux aboutit à un estimateur itératif de canaux et de symboles (ICSE) bien connu. L'EM-ICSE itère entre un estimateur de symbole basé sur la récursivité avant-arrière (égaliseur BCJR) et un estimateur de canal, et peut fournir des estimations approximatives de canal ...

Optimal channels for channelized quadratic estimators
Journal of the Optical Society of America A, 2016 We present a new method for computing optimized channels for estimation tasks that is feasible for high-dimensional image data. Maximum-likelihood (ML) parameter estimates are challenging to compute from high-dimensional likelihoods. The dimensionality reduction from M measurements to L channels is a critical advantage of channelized quadratic ...

Channel Performance Estimations with Extended Channel Probing
CoRR, 2021 We test the concept of extended channel probing in an Optical Spectrum as a Service scenario in coherent optimized flex-grid long-haul and 10Gbit/s OOK optimized 100-GHz fixed-grid dispersion-managed legacy DWDM networks. An estimation accuracy better than +/- 0.1dB in GSNR implementation margin is obtained for both networks by using flexible coherent ...
