It begins with an introduction to the basic ideas behind fixed and random access systems in order to demonstrate the difference between CDMA and the more widely understood TDMA, FDMA or CSMA. Secondly, a review of basic spread spectrum techniques are presented which are used in CDMA systems including direct sequence, frequency-hopping and time-hopping approaches. The basic concept of CDMA is presented, followed by the four basic principles of CDMA systems that impact their performance: interference averaging, universal frequency reuse, soft handoff, and statistical multiplexing. The focus of the discussion will then shift to applications. The most common application of CDMA currently is cellular systems. A detailed discussion on cellular voice systems based on CDMA, specifically IS-95, is presented. The capacity of such systems will be examined as well as performance enhancement techniques such as coding and spatial filtering. Also discussed are Third Generation CDMA cellular systems and how they differ from Second Generation systems. A second application of CDMA that is covered is spread spectrum packet r | | 出版日期 | Book 2006 | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-031-01673-8 | | isbn_softcover | 978-3-031-00545-9 | | isbn_ebook | 978-3-031-01673-8Series ISSN 1932-1244 Series E-ISSN 1932-1708 | | issn_series | 1932-1244 | | copyright | Springer Nature Switzerland AG 2006 |
