Experience

Research Assistant

Polytechnic Institute of NYU
(8 months)Greater New York City Area

● Research Assistant in Center for Advanced Technology in Telecommunications
●This project focus on Filter Bank Multicarrier (FBMC) system, cosine-modulated multitone (CMT), and staggered-modulated multitone(SMT).
● Focus on review and analysis three related papers, " Filter bank techniques for the physical layer in wireless communications", " Cosine Modulated and Offset QAP Filter Bank Multicarrier Techniques: A Continuous-Time
Prospect", and " Filter bank multicarrier techniques for cognitive radios".
● Implement SMT system on MATLAB, FBMC shows faster decayed band edge, less ICI, and higher transmit efficiency (by reducing CP) compared to OFDM.
● Implement Phase-Lock Loop in filter bank system to keep carrier tracking.

Algorithm developing engineer

Huawei
(4 months)Shanghai

● Assistant algorithm engineer in algorithm develop department, participate in “Frequency Domain Receiver"
● Implement channel estimation algorithm(MMSE) improvement method in frequency domain, and compare it with algorithm in Time Domain to proof enhancement of efficiency, base on C programming.
● Learn the testing signal method on different kinds of test machines.

Research Assistant in wireless communication.

East China University of Science and Technology
(1 year)Shanghai City, China
