Abstract :
In this paper, we investigated the influence of antenna diversity over capture effect, and calculated the throughput improvement in IEEE 802.11b WLAN at 11 Mbit/s. For the capture effect, we obtained exact closed-form solution for conditional capture probability in case of L-fold ideal selection diversity, and approximate closed-form solution for conditional capture probability in case of L-fold maximum selection diversity. These analytical expressions have general significance and can be used upon any other multiple access wireless networks.
