Need a Matlab Expert

I considered the multi-cell massive MIMO-OFDM system. In this system there is 1 desired cell, and 3 interfering cells. I have to calculate the channel in uplink. to calculate the channel the users will transmit the pilot symbols towards the base station (using the pilot pattern scheme 1 in the file). the receiving antennas at the base station will receive the pilot symbols and using those pilots estimate the channel. The ML technique is used to estimate the channel. Also ML is combined with Cramer Rao Bound to minimize the variance of the ML estimator. At the end of estimating the channel, Mean Squared Error(MSE) and Bit Error Rate (BER) should be calculated and plot in the graphs Basically users are transmitting OFDM symbols using the Pilot Pattern 1 & 2 towards the BS, and BS is using ML+CRB technique to estimate the channel project archives are attached i will share you
