When network is congested, packet collisions will happen and lead to severe throughput decrease. In this paper we propose a novel collision decoding method to decode collided packets, and thus increase network throughput. Our method is specifically designed for OFDM-based WLAN network. IFFT/FFT, channel influence and packet collisions effects are formulated as linear processes. Taking into account network features as random-jitter and retransmission, collision can be seen as a group of linear equations and solved. Simulation results show that by adopting collision decoding method, the network throughput can be improved significantly, especially when the network is congested. © 2012 Springer-Verlag Berlin Heidelberg.
