| Abstract: | We examine a multiple-access communication system in which multiuser detection is performed without knowledge of the number
of active interferers. Using a statistical-physics approach, we compute the single-user channel capacity and spectral efficiency
in the large-system limit and derive their limiting values for high SNR. |
