Low-complexity frequency domain frame synchronization for short-reach IM/DD optical fiber transmission systems.

We propose a low-complexity frequency domain frame synchronization method for short-reach intensity modulation and direct detection (IM/DD) systems. A four-level pulse amplitude modulation-training sequence (PAM4-TS) is specially designed for the proposed method, which has an obvious peak in the amplitude spectrum that is higher than the normal signal. The proposed method comprises a coarse synchronization stage and a fine synchronization stage.

Compensation schemes for uneven illumination and LED light-emitting instability in optical camera communication system.

In order to increase the data rate of the optical camera communication (OCC) system, the 8-composite-amplitude-shift-keying modulation (8CASK) OCC system is used in this work. However, if the static decision thresholds are employed to demodulate multi-level ASK signal, uneven illumination of LED lamps and LED light-emitting instability lead to the fluctuation of the gray range in the picture and degrade the bit-error-rate (BER) performance. In this work, we propose and demonstrate a demodulation scheme, using the uneven illumination compensation algorithm, the pixel matrix threshold overall update algorithm and the secondary decision algorithm, to mitigate the impact of illumination unevenness and LED light-emitting instability.

Accurate and Robust Monocular SLAM with Omnidirectional Cameras.

Simultaneous localization and mapping (SLAM) are fundamental elements for many emerging technologies, such as autonomous driving and augmented reality. For this paper, to get more information, we developed an improved monocular visual SLAM system by using omnidirectional cameras. Our method extends the ORB-SLAM framework with the enhanced unified camera model as a projection function, which can be applied to catadioptric systems and wide-angle fisheye cameras with 195 degrees field-of-view.

OSNR and nonlinear noise power estimation for optical fiber communication systems using LSTM based deep learning technique.

The optical signal-to-noise ratio (OSNR) and fiber nonlinearity are critical factors in evaluating the performance of high-speed optical fiber communication systems. Recently, several deep learning based methods have been put forward to monitor OSNR of a fiber communication system.

Fusion Based on Visible Light Positioning and Inertial Navigation Using Extended Kalman Filters.

With the rapid development of smart technology, the need for location-based services (LBS) increases every day. Since classical positioning technology such as GPS cannot satisfy the needs of indoor positioning, new indoor positioning technologies, such as Bluetooth, Wi-Fi, and Visible light communication (VLC), have already cut a figure. VLC positioning has been proposed because it has higher accuracy, costs less, and is easier to accomplish in comparison to the other indoor positioning technologies.

Gender effect on pre-attentive change detection in major depressive disorder patients revealed by auditory MMN.

Gender differences in rates of major depressive disorder (MDD) are well established, but gender differences in cognitive function have been little studied. Auditory mismatch negativity (MMN) was used to investigate gender differences in pre-attentive information processing in first episode MDD. In the deviant-standard reverse oddball paradigm, duration auditory MMN was obtained in 30 patients (15 males) and 30 age-/education-matched controls.
