摘要：
The throughput performance of ALOHA systems in mobile radio channels can be improved due to the capture phenomenon, meaning that the strongest packet may capture the receiver even in the presence of other overlapping packets. In this paper, the influence of receiver capture on the performance of ALOHA in the presence of shadowing is investigated. The combined effect of Rayleigh fading, log-normal shadowing, and spatial distribution of mobile users is also studied. The capture phenomenon results in substantial improvement in system throughput under slow fading. Under fast fading conditions, the throughput can also be increased especially when error-correction coding is used. © 1990, IEEE
