Pulse Construction in OFDM Systems Via Convex Optimization
In order to reduce the inter-carrier interference (ICI) produced by frequency offset in OFDM systems, we set up an optimization problem to find the transmission pulse which maximi...

Noise Model Analysis of Optimized Mixed-Radix Structures for Pulsed OFDM
Pulsed OFDM (P-OFDM) is a proposed enhancement to Multi-Band Orthogonal Frequency Division Multiplexing which reduces the power and complexity of Ultra Wideband transceivers witho...

OFDM Turbo DeCodulation with exit optimized bit loading and signal constellations
We propose the combination of Orthogonal Frequency Division Multiplexing (OFDM) and Turbo DeCodulation (TDeC) – a multiple Turbo process consisting of iterative demodulation and...

Swarming along the evolutionary branches sheds light on genome rearrangement scenarios
A genome rearrangement scenario describes a series of chromosome fusion, fission, and translocation operations that suffice to rewrite one genome into another. Exact algorithmic ...

A Theory of Aliasing Separation for Light Field Data
A light field means a 4-D function which characterizes the flow of light rays from a target scene, and used for image-based rendering. This paper presents a novel theoretical fr...
