Abstract. Interference cancellation procedure in a centralized wireless network is considered. The PHY layer of the network uses OFDM modulation, while the MAC layer employs random multiple access. The error probability of interference cancellation is estimated. The dependence of maximal stable throughput of multiple access algorithms on the SNR is derived.
