In the last decade, wireless communications research boosted launching new standards and proposing new techniques for the - cess technology. We moved from the UTRA standard capable to transmit 0. 5bit/s/Hz to WLAN which is promising 2. 7bit/s/Hz. Now wireless c- munication systems are facing a ?ourishing of new proposal moving from multiple antennas at transmitter and receiver side (MIMO systems), to new powerfulForwardErrorCorrectionCodes,toadaptiveradioresourcemana- mentalgorithms. Thenewchallenge,however,isthemovetowardsmultimedia communications and IP technology. This move implies e?orts in several new aspects. First of all an open network, as IP is, imposes the necessity of a - cure network, to guarantee the privacy of the ongoing communications, avoid the use of the networks by unauthorized customers, avoid the misuses and the charge to third parties of the cost of the connection. Also, quality of service (QoS) of the communications is becoming a must in IP networks which are carrying services which need a guaranteed QoS as telephony, real time s- vices, etc. To get this new target s | | 出版日期 | Conference proceedings 2007 | | 关键词 | 802; 11; Code Division Multiple Access; IEEE 80; Long Term Evolution; MIMO; Orthogonal frequency-division | | 版次 | 1 | | doi | https://doi.org/10.1007/978-0-387-73825-3 | | isbn_softcover | 978-1-4419-4476-4 | | isbn_ebook | 978-0-387-73825-3Series ISSN 1860-4862 Series E-ISSN 1860-4870 | | issn_series | 1860-4862 | | copyright | Springer-Verlag US 2007 |
