Das umfassende Lehrwerk Nachrichten?bertragung gliedert sich in vier Teile. Beginnend mit Grundlagen der Systemtheorie deterministischer und stochastischer Signale sowie einigen grunds?tzlichen Eigenschaften von ?bertragungskan?len widmet sich der zweite Teil der klassischen Analog?bertragung. Teil three behandelt ausschlie?lich die neueren digitalen Modulationsverfahren. Der vierte Teil wurde weitgehend neu gestaltet; er ist jetzt ausschlie?lich der modernen Mobilfunktechnik gewidmet. Zun?chst enth?lt er eine Zusammenfassung allgemeiner Zusammenh?nge, um sich dann dem aktuellen Mehrtr?gerverfahren OFDM und dem CDMA-Konzept zuzuwenden. Zur representation werden der moderne W-LAN-Standard und das Mobilfunksystem UMTS dargestellt. Den Abschluss bildet ein neues Kapitel ?ber Mehrantennen-Konzepte.

"Following within the footsteps of its well known predecessors, excessive energy Microwaves, 3rd variation maintains to supply a wide-angle, built-in view of the sphere of excessive strength microwaves (HPMs). This 3rd variation contains major updates in each bankruptcy in addition to a brand new bankruptcy on beamless platforms that covers nonlinear transmission strains. Written by means of an experimentalist, a theorist, and an utilized theorist, respectively, the booklet deals complementary views on diverse resource kinds. The authors handle: how HPM relates traditionally and technically to the traditional microwave box; the prospective purposes for HPM and the most important standards that HPM units need to meet that allows you to be utilized; how excessive energy resources paintings, together with their functionality functions and obstacles; [and] the vast primary concerns to be addressed sooner or later for a large choice of resource forms. The ebook is available to a number of audiences. Researchers at the moment within the box can widen their figuring out of HPM. current or capability clients of microwaves will realize some great benefits of the dramatically larger energy degrees which are being made on hand. novices to the sphere can pursue additional examine. choice makers in direct power acquisition and comparable fields, comparable to radar, communications, and excessive strength physics, can see how advancements in HPM will impact them." -- Publisher's description Read more...
