Past Research Projects

➢ The project will review the state of the art on linear and nonlinear predistortion applied to optical transmitters, as well as implement a few of the simple common methods.

➢ The project will investigate the use of ML tools for the compensation (pre- and/or post) of linear and nonlinear signal distortion caused by practical limitations of components employed in optical communication systems. 

➢ Designed a pair of smart glasses based on Raspberry Pi, which can realize the remote transmission of information (video, audio, text, photo, image, and voice control), and real-time fault detection in the smart glasses terminal to give feedback for better maintenance.

➢ Improved the YOLOV4-tiny target detection algorithm such as proposing a new network structure and post-process approach to have higher accuracy and high computational speed, and the GAN algorithm is used to create my own Insulator-Defect Datasets. Eventually, I deploy it on Raspberry Pi for real-time transmission line fault detection

➢ Alibaba Cloud server is used to build NodeJS server, and STUN / TURN server was used to achieve NAP penetration of two devices in different network environments. 

➢ Used Webrtc to easily implement voice and video calls. For the function of taking photos, the canvas command is used to intercept and draw the video in the video frame. Base64 encoding is used to encode the picture which is transmitted through p2p together with text. 

➢ Designed a multi-band, wide-band, high-gain microstrip antenna to efficiently collect RF energy in the frequency band mainly at 915MHz or 2.4GHz, and designed a matching circuit and voltage doubler rectification circuit which finally enables the system to be applied to low-power devices such as Zigbee. 

➢ Researched the application of metamaterials technology in antennas to achieve better performance while ensuring miniaturization, and used intelligent algorithms for antenna structure. 

➢ Designed a software that uses “BeiDou” data transparent transmission to realize the reading of various sensor data in remote environments through wireless transmission and real-time monitoring of the environment.

➢ Used QtCreator software for the development (Qt uses C++ for programming), RS485 bus to read data by wire, and then connectted BeDou to realize BeiDou communication

➢ On the basis of the RS485 bus, three different sensors can be read and recorded at one time. The sensor to be read and the corresponding reading interval can be set separately. The function of automatically searching the port and configuring the device number is realized. On the basis of realizing wired reading, BeiDou transparent transmission is used to achieve shortrange wireless data collection.
