Simulation and analysis of adaptive beamforming algorithms for phased array antennas

الملخص EN

Adaptive phased antennas, known as SMART ANTENNAS attract so much attention with the increase of wireless communications implementation.

The smart antennas can change their shape of transmission placing nulls in the direction of interference, and steer their main lobe to the direction of interest.

This process leads to maximizing Signal to Interference Ratio (SIR) maximizing the throughput of the network.

They can mitigate channel fading by searching for the best alternative path.

This paper investigates the principles and the algorithms used to steer the main lobe and shape the radiation pattern to optimize the performance.

Only analogue techniques are considered.
