The main research is on the wireless communication area. He has established several channel characteristics measurement systems, including narrowband and wideband measurement systems, vector wideband Channel Sounder, multiple-input-multiple-output
（MIMO）channel measurement systems etc.. He has conducted several projects on the third generation （3G） mobile communication systems, such as smart antenna technology, RAKE receiver, and subscriber geolocation.
The key feature of the research is to consider the real channel characteristics. From the measured channel data to simulate the wireless communication system and to evaluate the performance of the proposed algorithms. Future research will investigate advanced transmission techniques such as OFDM, MIMO, and Impulse Radio with higher frequencies, wider bandwidth and higher data rate.
