Abstract:

The paper is concerned with the principles and description of a wideband test system with the objective of measuring the complex transmittance of a line-of-sight LOS microwave radio link subject to fading and multipath. The technique which uses cross-correction between pseudo-binary random sequences falls into the realm of spread spectrum techniques. The system described is designed to cover 1 GHz bandwidth the complex transmittance matrix. Computer simulations and preliminary experimental results are presented together with a brief initial comparison with other systems. Author
