Research Assistant: Channel equalization and spatial diversity for 60 GHz outdoor networks (9/2011-current)
1) Combine the channel equalization technique and spatial diversity technique to overcome ISI as well as narrowband fadings
2) Employ analog multi-tone (AMT) technique to overcome the ADC constraints at high data rate on the order of Gbps

Research Assistant: 60 GHz indoor channel measurements (04/2010-06/2011)
1) Write the embedded software program for the high rate (200 Mb/s to 1000 Mb/s) data generation using Virtex-II Pro RocketIO Multi-Gigabit Transceiver (MGT)
2) Use frequency spectrum analyzer to analyze the received signal performance

Research Assistant: Channel modeling and antenna diversity analysis for outdoor millimeter wave mesh networks (04/2009-09/2011)
1) Using the ray-tracing technique to model the 60 GHz outdoor channel model for the lamppost deployment
2) Analyze multipath effect and propose corresponding antenna diversity technique

Teaching Assistant: Analog Communications (ECE 146A) (01/2009-04/2009) ECE146B (04/2011-06/2011)
