In this paper, we propose an enhanced multiuser eigen channel selection (E-MES) scheme for multiple-input multiple-output (MIMO) downlink transmissions based on sequential projection and zero-formi
Orthogonal frequency-division multiplexing (OFDM) and multiple-input-multiple-output (MIMO) are two key technologies adopted in future wireless communication systems, such as LTE/LTE-A.
The 5G air interface, namely, dynamic multiple access (MA) based on multiuser superposition transmission (MUST) and orthogonal multiple access (OMA), may require complicated scheduling and heavy si
We study polarization evolution during nonlinear pulse propagation through a one-dimensional photonic crystal and experimentally demonstrate that enhanced nonlinear interactions reduce the threshol
In this paper, we propose a novel model for estimating the quality of speech without the reference speech information.
Generalizing a conventional phase-shifted pilot (PSP) sequences and discrete Fourier Transform (DFT) based channel estimator to MIMO-OFDM systems with virtual subcarriers, this paper presents two e
Advanced features are continuously being introduced in 3GPP LTE advanced systems, such as carrier aggregation, coordinated multiple point transmission and reception, heterogeneous network enhanceme
Using the extractable bit error ratio of a wire-tapping eavesdropper as a security metric, we demonstrate that information scrambling significantly enhances the physical layer security in multiple-
We analyze the physical layer security of a communication scheme with a multiple antenna legitimate transmitter, employing transmit antenna selection (TAS), and a single antenna legitimate receiver
A self-phase modulation (SPM)-assisted polarization-mode-dispersion (PMD) monitoring scheme based on frequency-resolved state-of-polarization rotation is proposed.
