The proposed estimator consists of a Time-Domain (TD) index set estimation on the grounds that the leakage outcome followed through a low-complexity TD submit-processing to suppress the leakage. The performance and complexity of the proposed channel estimator are analyzed and established through computer simulation. Simulation outcome exhibit that the proposed estimator outperforms traditional estimators and provides near-most beneficial efficiency even as preserving the low complexity similar to the easy DWT (Discrete Wavelet Transform) head quartered channel estimator.
