Diversity Analysis in WIFI System

Wi-Fi, a Wireless Local Area Network technology has solely conquered the arena of short range wireless broadband systems. To support the existing system and to further enhance the measure of performance in multipath fading environment, Wi-Fi technology is intertwined with space diversity technique which is implemented using Alamouti coding and is then introduced with interleaving/scrambling technique to take the benefit of time diversity. Diversity technique has been an essential factor in improving the quality of the wireless system's operation by providing performance almost equivalent to that of the least distorted path among various multi paths at any given time and thereby accounting for the fading effect caused in corruptive communication channels.
