Synthesis of Linear Antenna Array Using Genetic Algorithm With Cost Based Roulette to Maximize Side Lobe Level Reduction
Adaptive beam forming is a signal processing technique in which the electronically steerable antenna arrays are used to obtain maximum directivity towards Signal Of Interest (SOI) and null formation towards Signal of NOt Interest (SNOI) i.e. instead of a single antenna the antenna array can provide improved performance virtually in wireless communication. The characteristics of the antenna array can be controlled by the geometry of the element and array excitation. But side lobe reduction in radiation pattern should be performed to avoid degradation of total power efficiency and the interference suppression must be done to improve the Signal to Noise plus Interference Ratio (SINR).
