Spatially Sparse Precoding in Millimeter Wave MIMO Systems
TLDR
We exploit the spatial structure of mmWave channels to formulate the precoding/combining problem as a sparse reconstruction problem. Expand

Low complexity precoding for large millimeter wave MIMO systems
TLDR
We exploit the structure of mmWave channels to formulate the precoder design problem as a sparsity constrained least squares problem. Expand

The capacity optimality of beam steering in large millimeter wave MIMO systems
TLDR
We consider both beamforming and multi-stream precoding in single user systems with large mmWave antenna arrays and show that the unconstrained capacity-achieving precoding solutions converge to simple beam steering solutions. Expand

Antenna Array Design for Multi-Gbps mmWave Mobile Broadband Communication
TLDR
We demonstrate the feasibility of mmWave mobile broadband (MMB) communication supporting multi-Gbps data rates via system design supporting beamforming, system performance and SINR geometry analysis. Expand

Channel Feasibility for Outdoor Non-Line-of-Sight mmWave Mobile Communication
TLDR
We show that a wide beam width, low gain antenna at the mobile receiver can capture more energy in scattered non-line-of-sight environments and thus, can provide more gain than a narrow beam, high gain antenna. Expand

Enhanced Cryptcoding: Joint Security and Advanced Dual-Step Quasi-Cyclic LDPC Coding
TLDR
We propose a novel Joint Security and Advanced Low Density Parity Check (LDPC) Coding (JSALC) method which outperforms other cryptcoding methods by over 1.5 dB while maintaining the AES-128 security level. Expand
