研究領域摘要:

吳教授的主要研究領域為光通信,電腦通信及通信系統。在光通信方面,吳教授研究完美差異碼,並應用此碼與干擾消除接收器結合成為目前性能最佳的同步光編碼通信系統。以完美差異碼為基礎‚放寬交互關連係數可延伸更多之光正交碼並應用於非同步系統。乙太被動光網路為未來寬頻接取網路最佳選擇‚吳教授亦從事此方面研究,現已實作10Gb/s /1Gb/s之乙太被動光網路,在電腦通信方面‚他提出一可變封包長度之交換器架構並分析其性能,同時已完成 8 x 8, 1Gb/s 的實體製作。同時亦探討光交換機之架構及性能分析。

Research Summary:

Professor Wu’s research interests include Optical communications, computer communications, and communications systems. He studies optical orthogonal codes (OOC). He investigates the perfect difference codes (PDC) which have the cross correlation value exactly equal to one. Combining these codes with multiuser interference cancellation receivers, Professor Wu’s group propose the best synchronous optical code division communications system, which is applicable to broadband access networks. Based on PDC and relaxing the cross correlation value to larger than one, one can get more OCCs which are suitable for asynchronous optical code division communications. Because the Ethernet passive optical network (EPON) is the most promising Candidate for broadband access networks. This group implements an optical code division based EPON with A 10Gb/s / 1.25Gb/s EPON transmission rate. For the computer communications, Professor Wu proposed a variable packet length Self-routing switch architecture. An 8x8 1Gb/s switch was demonstrated . Furthermore ,This group is investigating the feed forward and feedback type optical switches with various buffer management schemes under long range dependent traffic. The performance analysis and the best buffer management scheme will be reported.
