Adaptive Multiuser MCDM for Underwater Acoustic Communications
Song-Wen Huang, Dimitris A. Pados
Chirp signals have been exploited extensively in radar and underwater acoustic (UW-A) communication systems for their robustness to multipath and superior correlation properties. W…
Multicarrier Chirp-Division Multiplexing for Wireless Communications
Song-Wen Huang, Dimitris A. Pados
We propose a multicarrier chirp-division multiplexing (MCDM) system in which orthogonal chirp waveforms are utilized as frequency subcarriers. Orthogonal characteristics of chirp s…
Low-Complexity Decoder for Overloaded Uniquely Decodable Synchronous CDMA
Michel Kulhandjian, Claude D'Amours, Hovannes Kulhandjian +3
We consider the problem of designing a low-complexity decoder for antipodal uniquely decodable (UD) /errorless code sets for overloaded synchronous code-division multiple access (C…
M-ary Orthogonal Chirp Modulation for Coherent and Non-coherent Underwater Acoustic Communications
Song-Wen Huang, Dimitris A. Pados
We propose an orthogonal chirp waveform design for underwater acoustic (UW-A) communications and analyze the cross-correlation characteristics of orthogonal chirp waveforms in cohe…
L1-norm Principal-Component Analysis of Complex Data
Nicholas Tsagkarakis, Panos P. Markopoulos, Dimitris A. Pados
L1-norm Principal-Component Analysis (L1-PCA) of real-valued data has attracted significant research interest over the past decade. However, L1-PCA of complex-valued data remains t…
Efficient L1-Norm Principal-Component Analysis via Bit Flipping
Panos P. Markopoulos, Sandipan Kundu, Shubham Chamadia +1
It was shown recently that the L1-norm principal components (L1-PCs) of a real-valued data matrix ( data samples of dimensions) ca…
Increasing Indoor Spectrum Sharing Capacity using Smart Reflect-Array
Xin Tan, Zhi Sun, Josep M. Jornet +1
The radio frequency (RF) spectrum becomes overly crowded in some indoor environments due to the high density of users and bandwidth demands. To accommodate the tremendous wireless…
Optimal Algorithms for -subspace Signal Processing
Panos P. Markopoulos, George N. Karystinos, Dimitris A. Pados
We describe ways to define and calculate -norm signal subspaces which are less sensitive to outlying data than -calculated subspaces. We start with the computation of the…
Some Options for L1-Subspace Signal Processing
Panos P. Markopoulos, George N. Karystinos, Dimitris A. Pados
We describe ways to define and calculate -norm signal subspaces which are less sensitive to outlying data than -calculated subspaces. We focus on the computation of the $…
Waveform Design for Secure SISO Transmissions and Multicasting
Ming Li, Sandipan Kundu, Dimitris A. Pados +1
Wireless physical-layer security is an emerging field of research aiming at preventing eavesdropping in an open wireless medium. In this paper, we propose a novel waveform design a…
