Wenson Chang professor
    Wireless communication and network laboratory (WCN) was founded by Dr. Chih-Wen (Wenson) Chang in Department of Electrical Engineering, National Cheng Kung University in August 2006. The current research interests of the WCN Lab include radio resource management (RRM) and cross-layer optimization for the wireless communication systems. Recently, we have investigated several critical RRM issues for the 3.5G, 4G and more advanced wireless communication systems, e.g. WCDMA, HSPA, MC-CDMA, OFDM-based and CR systems.
Now, we are interested in the following and related issues:

1. Radio resource management for the 4G, 5G, femto-cell systems and CR network.
2. Performance analysis and optimization for cooperative communication system.
3. Application of Game theory to the wireless communication systems.
4. Adaptive cellular architecture design, including adaptive frequency planning and sectoring with aids of distributed antenna system and relays.
5. Cross-layer design and optimization for advan.
