5G NR, 4G LTE, Wi-Fi Radio Access Algorithm & Architecture Digital Signal Processing

Next-Gen Physical Layer NOMA, MUST Mobile Communications Unix and Linux PROFESSIONAL EXPERIENCE AND PROJECTS

Substitute Civilian Serviceman, Aviation Police Bureau, TSA airport, Taipei, Taiwan Aug,2017-Aug,2018

Built/maintained a database to organize lost-and-found property and designing an ID checking program.

Assisted the aviation police with safeguarding, traffic administration, crime investigation, and security. Research Assistant (MediaTek & Asus Projects), National Taiwan University, Taipei City, Taiwan Jan,2015-July,2017

Solved problems related to NOMA, 3GPP, LTE, and D2D technologies after researching the source of discrepancies and assessing appropriate correction options.

Applied the HARQ-CC and AMC to the NOMA system with codeword-level SIC receiver.

Designed a new proportional fairness scheduling prevent from continuously serving cell edge users and achieve better performance in cell edge and average throughput.

MediaTek Project: Represented NTU/MediaTek in 3GPP standardization meetings and simulated a model of multifaceted 3GPP LTE/5G NR (NOMA) model at the System/Link Level in C.

Worked on ASUS Project as a joint inventor of a D2D application and a patent co-author, providing potential ideas/technologies for ASUS wireless department.

Proposed a method determining whether to performing a D2D transmission and a cellular transmission simultaneously in a resource block allocated in a cellular uplink time slot. It has the advantage of frequency reuse, but does not need centralized interference management. Wireless System Software Engineer, IoT Eye (Startup), Princeton University, New Jersey, USAAug,2015-Dec,2015

Succeeded in implementing OpenAirInterface, a Software-defined radio (SDR) which is a radio communication system network with eNB, gNB and 4G, UE as well as the core network EPC and 4G-CN, on a Universal Software Radio Peripheral USRPTM platform.
