Abstract

This paper presents the measurement and statistical analysis of the temporal variations of the radio channel defined by a fixed link at 3.5 GHz in suburban areas. The analysis provides the required information about the temporal stability of the channel, the probability of occurrence and depth of fades, the Doppler spectrum and, in general, the influence of the environment on the signal behaviour. In particular, the effect of fast traffic on a motorway in the neighbourhood of the receiver is investigated, obtaining some general conclusions particularly useful in wireless communication systems design.

Additional information

Rafael P. Torres was born in M´laga, Spain, in 1961. He received his MS degree in Physics from the University of Granada (Spain) in 1986 and his Ph.D. from the Telecommunications Engineering School at the Polytechnic University of Madrid (UPM) in 1990. From 1986 to 1990 he was with the Radio Communication and Signal Processing Department of the UPM as a research assistant. During this time, he worked about numerical methods in electromagnetics, and its applications to design of passive microwave devices like radomes, circular polarizer, rotators and planar lenses. He became an associate professor in the Department of Communication Engineering of the University of Cantabria (Spain) in 1990. From this time to the present, he has participated in several projects about RCS computation, on board antennas analysis, electromagnetic compatibility, and radio-propagation. He is co-author of a book about the CG-FFT method, author of several chapters in different books, more than 20 papers, and about 80 conference contributions. He has been the leader of the group that have developed the code CINDOOR, Computer Tool for Planning and Design of Wireless Systems in Enclosed Spaces. His current research interests include radio-propagation for wireless and mobile communications, as well as the simulation and design of new wireless communications systems.

Francisco Medina was born in Santander, Cantabria (Spain), in July 1974. He received the M.Sc. degree in telecommunications engineering from the University of Cantabria, Spain, in 2002. During three months in 2002 he hold a scholarship to stay at Bordeaux (France) and to work in the company Thalès Systèmes Aéroportés. Nowadays he works as a sales engineer at the Export Department of Nexans in Maliaño, Cantabria (Spain), an expert company in cables and cabling systems.

Susana Loredo was born in Gijóon, Spain, in 1972. She received the M.S. and Ph.D degrees in telecommunications engineering from the University of Cantabria, Spain, in 1997 and 2001 respectively. From 1998 to 2001 she was with the Department of Communications Engineering as a Research Assistant. During this time, she worked on numerical and high frequency methods applied to the characterization of the radio-propagation channel, and also on the narrowband and wideband experimental characterization of the indoor radio channel. In 2001 she joined the Department of Electrical Engineering at University of Oviedo, Spain, as a Research Scientific. From this time to the present, she has been working on MIMO channel characterization using high frequency approaches and source reconstruction methods to characterize the antenna radiation.
