Collision resolution in slotted Aloha smart antenna system using pdf estimation-based blind criteria

Abstract

In this paper we apply a probability density func-tion (pdf) estimation-based adaptive blind criterion to the problem of collision resolution in Slotted ALOHA (S-ALOHA) protocol. The approach we follow is based on the computation of the bit error rate through numerical simulations. The performance of the proposal is compared with other blind criteria and simulation results show its good trade-off between performance and computational complexity.
