EM-based Semi-blind Channel Estimation in AF Two-Way Relay Networks
Saeed Abdallah, Ioannis N. Psaromiligkos
We propose an expectation maximization (EM)-based algorithm for semi-blind channel estimation of reciprocal channels in amplify-and-forward (AF) two-way relay networks (TWRNs). By…

Exact Cramer-Rao Bounds for Semi-blind Channel Estimation in Amplify-and-Forward Two-Way Relay Networks
Saeed Abdallah, Ioannis N. Psaromiligkos
In this paper, we derive for the first time the exact Cramer-Rao bounds (CRBs) on semi-blind channel estimation for amplify-and-forward two-way relay networks. The bounds cover a w…
