Manipulating an optical field is especially required when light can be controlled by light itself, with novel properties emerging in connection with the optical beam having complex structures. Research on a structured light and the optical angular momentum has cultivated a new, vigorous and distinctive interdisciplinary area, with strong interest and activity worldwide. In this work, a caustic vector...
Combining coding, modulation, transmit and receive diversity, and validly increases the anti-noise performance in fading channels, OSTBC (orthogonal space-time block codes) is a new channel coding technology accompanying with the extensive application of wireless communication. Based on typical channel model of the OSTBC in MIMO (multiple-in, multiple-out) wireless communication channels, a general...
In connection with increasingly extensive application of wireless spread spectrum system and problems in interference aggravated continuously, this paper proceeds thorough research on the performance of direct sequence spread spectrum (DSSS) system with short spreading codes against interference. Particularly , in view of effects to system performance resulted from single frequency interference, based...
