Blind channel estimation for MPSK-based amplify-and-forward two-way relaying
We consider the problem of channel estimation for amplify-andforward (AF) two-way relay networks (TWRNs). The majority of works on this problem develop pilot-based algorithms that...

Can one hear the shape of a room: The 2-D polygonal case
We consider the problem of estimating room geometry from the acoustic room impulse response (RIR). Existing approaches addressing this problem exploit the knowledge of multiple RI...
