In telecommunications, a diversity scheme refers to a method for improving the reliability of a message signal by using two or more communication channels with different characteristics. Diversity is mainly used in radio communication and is a common technique for combatting fading and co-channel interference and avoiding error bursts. It is based on the fact that individual channels experience different levels of fading and interference. Multiple versions of the same si… Web3. jún 1998 · Benefits of using space diversity are the proven improvement in uplink performance for reception of both mobiles and portables. The negative of space diversity would be that a suitable structure is required to allow for the ten wavelength spacing of the two receive antennas.
