The throughput performance of some multiaccess wireless systems is compared on the basis of the average energy per successfully received information bit E b =N0. We prove that, for an optimal choice of the system parameters, some systems are not interference limited and have a similar behaviour: at high E b =N 0 they \self-orthogonalize", i.e., on the average only one user per degree of freedom is active, while at low E b =N 0 they have the same throughput of conventional CDMA, achieved by infinite users per degree of freedom transmitting with vanishing rate.
