Peer - to - Peer Low Antenna Outdoor Radio Wave Propagation at 1 . 8 Ghz
نویسنده
چکیده
In this outdoor propagation study, low antenna heights of 1. 7 m are used at both the transmitter and the receiver to measure wideband (100 MHz baseband) power-delay profiles (PDPs) of the channel for a peer-to-peer communications system operating at 1.8 GHz. Rural and urban areas are studied in 22 different transmitter-receiver links, and the path loss and delay spread characteristics are presented. The small-scale multipath fading characteristics are measured in detail by recording 160 PDPs within each local area. This paper shows the measurement setup for calculation of the fading rate variance and the estimation of the angular spread of each multipath component. The accuracy of the angular spread is discussed.

With the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. Many site-specific methods have been proposed for modeling indoor radio channels. Among these methods, the ray tracing algorithm and the finite-difference time domain (FDTD) method are the most popular ones. The ray tracing approach ...
