Linear antenna array adaptive beamforming for space-time signal processing using hybrid genetic algorithms applied to fading channels

In Today’s World, the Wireless Community is in great demand of Increasing capacity and to provide high data rate services due to increase in the number of users and traffic due to a paradigm shift in the existing technology to support Internet Application domain due to the increased popularity of Broadband Wireless Access (BWA). The 2.4 GHz licenced band caters to a variety of applications and 5850-5925 MHz for Automotive Radar Applications. Smart Antenna Arrays here are finding wide popularity in the EM community because they have a potential to provide both high capacity by dynamically tuning Interference in real time Environment (automotive motion, aerodynamics) by adjusting the weights, separations as well as appropriatephases and have potential applications in spacial Signal processing such as DOA estimation, adaptive beamforming and other DSP applications. The ability to adapt the radiation pattern (sidelobe, main beam direction, nulls, beamwidth) have been studied in this paper.
