Nonlinear Channel Estimation Error Effect on Capacity of MIMO System
Abstract
This paper presents the effect of nonlinearity and the effect of estimation error on the channel capacity in MIMO system. We consider a nonlinear MIMO channel, and compare the capacity of Rayleigh MIMO channel model with estimation error with the nonlinear model, at different estimation errors. We consider the estimation error as Gaussian distribution. The simulation results show that the channel capacity of linear and nonlinear MIMO channels are sensitive to the channel estimation error, and due to the nonlinearity, the capacity is less than linear channel.
Keywords: MIMO, MIMO Modeling, channel capacity, channel estimation error, nonlinear MIMO channel.
