Optical Fiber Communication (OFC) Conference
作者: F. Devaux A. Carenco France Telecom Bagneux France
Summary form only given. Electroabsorption (EA) modulators were primarily intended for high-speed coding as an alternative to LiNbO/sub 3/ Mach-Zehnder modulators. Beyond this application, EA modulators have been incr... 详细信息

IEEE Conference on Vehicular Technology (VTC)
作者: H. Murata S. Yoshida Department of Electronics and Communication Kyoto University Sakyo Kyoto Japan
Co-channel interference is a major impairment limiting the capacity of cellular radio systems. In order to mitigate its effect, a trellis-coded co-channel interference canceller (TCC) has been proposed which makes use... 详细信息
