Journal ArticleDOI
Indoor Channel Characteristics for Visible Light Communications
TL;DR: This letter generalizes the Barry's model by including wavelength-dependent white LED characteristics and spectral reflectance of indoor reflectors and shows that the VLC provides a larger transmission bandwidth than infrared communications.
Journal ArticleDOI
Modulations for Visible Light Communications With Dimming Control
Kwonhyung Lee,Hyuncheol Park +1 more
TL;DR: In this paper, a multiple pulse position modulation (MPPMPM) was proposed to offer both functions of modulating data-stream and controlling the brightness at the same time, according to the dimming level.
Journal ArticleDOI
Performance Analysis of MIMO System with Linear MMSE Receiver
TL;DR: This paper considers the uncoded multiple-input multiple-output (MIMO) system with linear minimum mean square error (MMSE) detection under ideal fast fading, and presents new approximation for the Gaussian Q-function driven by numerical simulation.
Journal ArticleDOI
Efficient DFT-based channel estimation for OFDM systems on multipath channels
TL;DR: An improved discrete Fourier transform (DFT)-based channel estimation for orthogonal frequency division multiplexing systems is proposed and can improve the performance by deciding significant channel taps adaptively without requiring any channel statistical information.
Proceedings ArticleDOI
Modulation analysis for wireless infrared communications
Hyuncheol Park,John R. Barry +1 more
TL;DR: This paper examines the performance of several modulation schemes on the indoor wireless optical channel, and compares the power and bandwidth efficiency of several forms of P PM, including multiple PPM, overlapping PPM.
