Based on the Jake model, we derive the new autocorrelation function and propose a universal minimum mean square error (MMSE) channel estimator based on the new autocorrelation function. Therefore, due to its inherent robustness, the proposed MMSE channel estimator can be used for various channel scenarios. The performance of MMSE channel estimator is studied through the practice of DVB-T standard, which indicates that MMSE channel estimator can achieve the least squared error performance with low complexity.
