The last decade has witnessed a large increase in the usage of spread spectrum systems. Even though SS techniques were initially used for military applications, commercial applications are now growing far more rapidly. New SS schemes that exploit more complex modulation and multiple access techniques offer improved capacity and performance. Use of antenna arrays is yet another multiplier for SS network capacity. We can expect to see a growing importance of improved SS systems in the future. In fact, third generation wireless networks are likely to adopt wideband CDMA in preference to TDMA, which was popular in second generation systems. [ABSTRACT FROM AUTHOR] |
