Abstract: We proposed Modified Conjugate Gradient Total Least Square (MCGTLS) method to estimate the 5G Communication system. The proposed MCGTLS will increase the system performance by cancelling the Inter symbol Interference and Inter carrier Interference. Here the interferences are not treated as AWGN. The operation of matrix becomes perplexed, thus obtaining accurate simulation results to validate the performance of MCGTLS method. The obtained Results are compared with theoretical analysis under large different normalized Doppler frequencies with different modulation techniques like QAM and MQPSK.
