The wireless propagation channel is characterized by a spatiotemporally varying transfer function, which presents very interesting properties , but also causes severe impairments during the implementation of a telecommunications system. A signal propagating through the wireless channel will in general arrive at the receiver after reflection, refraction and diffraction, i.e. scattering. This causes rapidly fluctuating instantaneous signal strength, and a non-constant local mean and area mean signal power. These phenomena will in turn severely deteriorate the quality of the received signal.
Smart antennas are proposed in order to affront multipath fading. By using a smart antenna at the transmitter, receiver or both, a satisfactory mitigation of this phenomenon is being made possible, with a proven beneficial impact to the performance of a telecommunications system.
In this presentation, multipath fading is examined, while a genetic algorithm is proposed for the design of smart antennas with multipath-combat characteristics. On this basis, a large number of antenna array designs, with interesting and novel characteristics, are presented. Moreover, stochastic and deterministic channel modeling and simulation tools are developed, incorporating the capability of evaluation of smart antennas' effect. Finally, a number of smart antenna systems and sub-systems are implemented, and their performance is evaluated in a real, strong multipath indoor environment. Thus, their eligibility and capability of mitigating multipath fading is proven in practiceThe wireless propagation channel is characterized by a spatiotemporally varying transfer function, which presents very interesting properties , but also causes severe impairments during the implementation of a telecommunications system.
