Group B

Research Target: To develop super-high-speed coherent optical communication technology, broadband wireless signal processing technology, secure network architectures, and communications protocols, as well as optical and wireless technologies and distributed networks. The target data rate of optical communications is 1~10 Tbps using optical TDM/WDM technology and the wireless data rate should be as high as 100 M~1 Gbps over a hostile wireless propagation channel.
