Investigation of the Noise Immunity of MMSE and ZF Algorithms in MIMO Systems under Conditions of Correlated Fading

This report analyzes the performance of a single-user wireless telecommunication system model with MIMO technology under conditions of spatially correlated channel fading. Various linear receivers used in MIMO systems are examined, including the Minimum Mean Squared Error Detection algorithm and the Zero Forcing algorithm. The report also presents plots of interference immunity for both QPSK and QAM-64 modulation methods at different levels of spatial fading correlation in the MIMO channel, as well as cases of some antenna configuration usage (8×8 and 4×4). Conclusions are drawn based on the statistical simulation results obtained regarding the impact of spatial fading correlation on the interference immunity of MIMO systems under various conditions.
