Abdelhamid Ladaycia, Marius Pesavento, Anissa Mokraoui, Karim Abed-Meraim, Adel Belouchrani

ICASSP 2019accepted

This paper deals with semi-blind channel estimation in Single-Input Single-Output (SISO) Orthogonal Frequency Division Multiplexing (OFDM) communications system. The proposed algorithm proceeds in two main stages. The first one addresses the pilot-based Time-Of-Arrival (TOA) estimation using subspac…

Em-Based Semi-Blind Mimo-Ofdm Channel Estimation

Abdelhamid Ladaycia, Adel Belouchrani, Karim Abed-Meraim, Anissa Mokraoui

ICASSP 2018accepted

This paper deals with semi-blind (SB) channel estimation of Multiple-Input Multiple-Output Orthogonal Frequency-Division Multiplexing (MIMO-OFDM) wireless communications system in the uplink transmission. Herein, we propose a new channel estimation approach using the well known EM technique. More pr…
