Performance Indicator for MIMO MMSE Receivers in the Presence of Channel Estimation Error
Performance Indicator for MIMO MMSE Receivers in the Presence of Channel Estimation Error
We present the derivation of post-processing SNR for minimum mean-squared error (MMSE) receivers with imperfect channel estimates, and show that it is an accurate indicator of the error rate performance of MIMO systems in the presence of channel estimation error. Simulation results show the tightness of the analysis.
