Fettweis lGerman Aerospace Research Establishment (DLR) Institute for Communications Technology 0-82234 Oberpfaffenhofen, Germany lDresden University of Technology Department of Electrical Engineering 0-01062 Dresden, Germany To operate future generation multimedia communications systems high data rate transmission needs to be guaranteed with a high quality of service. For instance, the third generation cellular mobile systems should offer a high data rate up to 2 Mbitls for video, audio, speech and data transmission [1]. In addition, the important challenge for these cellular systems will be the choice of an appropriate multiple access scheme. These trends motivated many researchers to look for multiple access systems that offer high spectral efficiency. The technique of spread spectrum originating from the military applications may allow partly to fulfill the above requirements. Advantages of spread spectrum technique are broadly known: High immunity against multipath distortion, no need for frequency planning, high flexibility, easier variable rate transmission etc. [1-2]. A multiple access scheme based on direct sequence spread spectrum, known as d | | 出版日期 | Book 1997 | | 關鍵詞 | Audio; Modulation; Phase; communication; communication system; data transmission; multimedia; network; neura | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4615-6231-3 | | isbn_softcover | 978-1-4613-7858-7 | | isbn_ebook | 978-1-4615-6231-3 | | copyright | Springer Science+Business Media Dordrecht 1997 |
