Sparsity-aware sphere decoding: Algorithms and complexity analysis
Somsubhra Barik, Haris Vikalo
Integer least-squares problems, concerned with solving a system of equations where the components of the unknown vector are integer-valued, arise in a wide range of applications. I…

Full-Rate Full-Diversity Achieving MIMO Precoding with Partial CSIT
Biswajit Dutta, Somsubhra Barik, A. Chockalingam
In this paper, we consider a multiple-input multiple-output (MIMO) channel subjected to block fading. Reliability (in terms of achieved diversity order) and rate (i…

FRFD MIMO Systems: Precoded V-BLAST with Limited Feedback Versus Non-orthogonal STBC MIMO
S. Barik, Saif K. Mohammed, A. Chockalingam +1
Full-rate (FR) and full-diversity (FD) are attractive features in MIMO systems. We refer to systems which achieve both FR and FD simultaneously as FRFD systems. Non-orthogonal STBC…
