Analysis of capture probability performance techniques for wireless LAN
Junhui Zhao, Okechukwu C. Ugweje · 2003
The ability of a receiver to capture the intended signal in the presence of interference can improve the throughput of random multiple access protocols in wireless LAN (WLAN) applications. We investigate various methods of evaluating capture probability. We are concerned with the performance of a number of users in a WLAN infrastructure attempting to send data packets over a commonly shared carrier sense multiple access with collision avoidance (CSMA/CA) channel to a central access point (AP). The probability of capture when fading and multipath are present is analyzed and compared. The system performance in the presence of multipath fading is evaluated.
