Abstract :
The slotted ALOHA (S-ALOHA) scheme in Nakagami fading channel with the presence of in-cell and cochannel-cell interference is studied. The cases of asynchronous cochannel-cells are especially considered. The analysis is based on the signal capture model and gives closed-form expressions for the system throughput. Additional channel conditions and system parameters are examined in the study, including a minimal signal power requirement, lognormal shadowing and the cellular cluster size.
