Beamforming, multiplexing, and diversity are techniques used in communication systems, but they serve different purposes and operate in distinct ways. Here are the key differences between them: Beamforming: Beamforming is a signal processing technique used in antenna arrays to focus the transmitted or received signal in a specific direction . It aims to enhance the signal strength and quality in a desired direction while suppressing interference or noise from other directions. Beamforming can be used for both transmission and reception. Beamforming is particularly useful in wireless communication systems, such as cellular networks and Wi-Fi, where it improves signal reception at the user's location and increases overall system capacity. By directing the signal towards the intended receiver, beamforming can enhance the signal-to-noise ratio, extend coverage range, and improve system performance. Multiplexing: Multiplexing involves combining multiple signals or data streams into ...
