Zustand: Hervorragend | Sprache: Englisch | Produktart: B�cher | A critical issue for designers of communication systems is the characterization of the communication channel. The free-space propagation model does not adequately predict the mean path loss in space-to-ground communication systems. Traditional methods for predicting the effect of terrain impacting the path of propagating signals focus on statistical or empirical models, which can not always be extrapolated to model prevailing physical conditions. This study focuses instead on the development and application of knife-edge and rounded obstacle terrain models. The models are based on the geometric theory of diffraction and predict the attenuation affects due to diffraction caused by signal propagation over terrain.

Store Description

Seit �ber 30 Jahren handeln wir mit B�chern. Begonnen hat alles als kleiner Fachbuchhandel in Berlin. Heute sind wir spezialisiert auf den An- und Verkauf gebrauchter B�cher. Noch immer liegt unser Fokus dabei auf den Kategorien: Fachbuch und englischsprachige Literatur. Hinzu kommen B�cher aus allen anderen Genres, wie Belletristik, Biografien oder Kinderb�cher. Unser oberstes Ziel ist dabei die Weiterverwendung von Dingen und die Schonung von Ressourcen. Neben dem Ankauf von privaten B�chern oder Haushaltsaufl�sungen kaufen wir bundesweit komplette Bibliotheken und Buchbest�nde von Institutionen auf, um diese nachhaltig ein weiteres Mal auf den Markt zu bringen. Parallel dazu bietet Buchpark die M�glichkeit, gro�e Mengen einzulagern. Ganze Bibliotheken und umfangreiche Buchbest�nde werden von uns professionell auf Qualit�tsmerkmale hin untersucht und sorgf�ltig f�r den Onlinehandel aufbereitet. Wir schenken B�chern ein zweites Leben.
