Applying the relaying concept to a Code Division Multiple Access (CDMA) mobile network is not a new idea, and many such systems employing relaying capabilities have been suggested. An obstacle to their evaluation with respect to capacity and coverage gains over the conventional non-relaying networks has been the inapplicability of the existent path loss models for low height terminal communications. Herein, empirical propagation models for relaying systems with low height terminals are proposed. The new models consist of line of sight and non-line-of-sight branches, and they take...

Earthquakes represent a natural phenomenon that throughout human history has caused destruction of man-made structures and dramatic loss of life. This edited volume consists of a collection of ten chapters that address three topical areas related to earthquake research.
