Wen Y, Wen S, Hsu L, Chi S
Sensors (Basel) . 2022 Nov; 22(21). PMID: 36366197
The spectrum of light captured by a camera can be reconstructed using the interpolation method. The reconstructed spectrum is a linear combination of the reference spectra, where the weighting coefficients...

Wen Y, Wen S, Hsu L, Chi S
Sensors (Basel) . 2022 Aug; 22(16). PMID: 36016049
The recovery of surface spectral reflectance using the quadcolor camera was numerically studied. Assume that the RGB channels of the quadcolor camera are the same as the Nikon D5100 tricolor...

Wen Y, Wen S, Hsu L, Chi S
Sensors (Basel) . 2022 Jul; 22(13). PMID: 35808412
Surface spectral reflectance is useful for color reproduction. In this study, the reconstruction of spectral reflectance using a conventional camera was investigated. The spectrum reconstruction error could be reduced by...

Entropy (Basel) . 2021 Apr; 23(4). PMID: 33807223
Gait stability has been measured by using many entropy-based methods. However, the relation between the entropy values and gait stability is worth further investigation. A research reported that average entropy...

Entropy (Basel) . 2020 Dec; 22(10). PMID: 33286896
The complexity and the disorder of a 1/fα noise time series are quantified by entropy of entropy (EoE) and average entropy (AE), respectively. The resulting EoE vs. AE plot of...

Tsai C, Li C, Lin C, Lin C, Chi S, Lin G
Sci Rep . 2018 Sep; 8(1):13711. PMID: 30209333
With the remote beating of two mutually incoherent laser carriers, the local-oscillator-free long-reach millimeter-wave over fiber (MMWoF) link at 60-GHz band is demonstrated. The unique schemes of the proposed MMWoF...

Lin C, Lin C, Wei C, Chi S
Opt Express . 2017 Nov; 25(22):27750-27757. PMID: 29092245
This paper presents a DFT/IDFT-free receiving scheme for spread-OFDM signals. Leveraging sub-Nyquist sampling and proper sampling delay, the proposed scheme enables each user to receive the requested data without the...

Lin S, Cho S, Chou S, Lin J, Lin C, Chi S, et al.
Opt Express . 2014 Jul; 22(12):14944-57. PMID: 24977588
Based on a vector wave theory of volume holograms, dependence of holographic reconstruction on the polarization states of the writing and reading beams is discussed. It is found that under...

Huang H, Liang W, Lin C, Wei C, Chi S
Opt Express . 2014 Mar; 22(4):3938-43. PMID: 24663714
This study extended the transmission distance of a 100-GHz DD-OFDM-RoF system through the reduction of chromatic dispersion-induced phase noise. The implementation of a pilot-aided phase noise suppression (PPNS) scheme enabled...

Ho C, Lin C, Cheng Y, Huang H, Wei C, Chi S
Opt Express . 2014 Mar; 22(4):3911-7. PMID: 24663711
With broader available bandwidth, W-band wireless transmission has attracted a lot of interests for future Giga-bit communication. In this article, we experimentally demonstrate W-band radio-over-fiber (RoF) system employing single-sideband single-carrier...
