In this paper, the effect of imperfect channel state information at the receiver, which is caused by noise and other interference, on the multi-access channel capacity is analyzed by means of a statistical-mechanical approach. Replica analysis focus on analytically studying how the minimum mean square error (MMSE) channel estimation error appears in the multiuser channel capacity formula and mathematical...
In this paper, the effect of channel estimation error at the receiver on the multi-access channel capacity is analyzed under the framework of a statistical-mechanical approach. The multiuser channel capacity with or without channel estimation error is derived. Numerical simulation results are shown to validate the Asymptotic analysis. The simulation results demonstrate how the system parameters, such...
