Wireless Communication Technologies 16:332:559 (Advanced Topics in Communications)
Spread spectrum communications were originally developed for military purposes to capitilize on their desirable antijam (AJ) and low probability of intercept (LPI) properties. Since 1980s and early 1990s, though, application of the same in civilian communications has been worked upon. CDMA, based on spread spectrum communications technology, has been recognized as a viable alternative to FDMA a...

متن کاملTopics in Personal Communications Convientional Detection
Direct-sequence code-division mult ip le access (DS-CDMA) is a popular wireless technology. in DS-CDMA communications, all of the users’ signals overlap in t ime and frequency and cause mutual interference. The conventional DS-CDMA detector fo l lows a single-user detection strategy in which each user is detected separately w i thou t regard for the other users. A better strategy is mult i-user...

متن کاملPolarization in Wireless Communications
Wireless communications exploits the electromagneticmedium,which is intrinsically polarization-sensitive. Much wireless technology, however, has been devised without explicit consideration of polarization. Past decades of wireless technology has mainly exploited the dimensions of time, frequency and space. As such, polarization is a logical next step in this progression. This special issue focu...
