Statistical Physics Analysis of Maximum a Posteriori Estimation for Multi-channel Hidden Markov Models
Avik Halder, Ansuman Adhikary
The performance of Maximum a posteriori (MAP) estimation is studied analytically for binary symmetric multi-channel Hidden Markov processes. We reduce the estimation problem to a 1…

Joint Spatial Division and Multiplexing
Ansuman Adhikary, Junyoung Nam, Jae-Young Ahn +1
We propose Joint Spatial Division and Multiplexing (JSDM), an approach to multiuser MIMO downlink that exploits the structure of the correlation of the channel vectors in order to…

On the Coexistence of Macrocell Spatial Multiplexing and Cognitive Femtocells
Ansuman Adhikary, Giuseppe Caire
We study a two-tier macrocell/femtocell system where the macrocell base station is equipped with multiple antennas and makes use of multiuser MIMO (spatial multiplexing), and the f…
