Improvement of Reliable Data Transmission Signal by Space Diversity Technique in Wireless Communication

The use of space diversity technique in wireless communication is a method of improving signal quality and mitigating interference and fading in long-distance wireless communication systems. Space diversity is a type of antenna diversity technique where two or more antennas are used at different locations to transmit or receive a signal in order to overcome signal fading due to a variety of conditions such as shadowing, multipath fading, and diffraction. In this technique, antennas are spaced apart by a certain distance completing both a vertical and horizontal separation. This allows the signal to pass through different paths, thus providing a more reliable communication signal, with less interference and signal attenuation. In addition, space diversity can also alleviate beam squint in directional antennas, which is responsible for the weakening of signal strength when the signal source is located in a plane perpendicular to the main lobe of the antenna. The additional signal paths also help to improve link reliability if any one of them fails due to multipath fading. As a result, space diversity is an advantageous technique for providing improved communications with improved signal quality.
