| Abstract(in English) | This report considers multi-cell Massive multiple-input/multiple-output (MIMO) system. We evaluated the spectral efficiency (SE) for both Uplink and Downlink using the estimated channels with minimum mean-squared error (MMSE) and zero-forcing (ZF). Through simulation results, we show that by comparing MMSE and ZF methods in both perfect channel state information (CSI) scenario and imperfect CSI scenario, the performance of SE will tradeoff between performance regression and complexity of MMSE and ZF methods. |
