摘要：
A Least Squares Channel Estimation (LSCE) method is designated for a Massive MIMO system combined with Orthogonal Frequency Division Multiplexing (OFDM). The Mean Square Error (MSE) of LSCE is computed firstly in a Rayleigh fading channel. Secondly, if channel estimation was available at the receiver (Base Station), the data detection could be made by linear and nonlinear detectors i.e (ZF, MMSE) and (SNR-Based Ordering, OSIC-SINR-Based Ordering) respectively. Simulation results show that by increasing antennas number of Base Station (BS), the nonlinear detectors perform more in terms of Bit Error Rate (BER).
