The algorithm proposed in this Article is intended for estimated accuracy and network throughput, two indexes of LTE channel, to design an approach for improvement of algorithm, and linear least square algorithm by using of weighted multilayer time-frequency domain LTE-OFDM resource model, for estimation of weighting parameters and the 2D spread spectrum power normalization algorithm. The results of simulation comparison on standard model database show that, while improving estimated accuracy, algorithm proposed in this Article can also remain network throughput at a high level, which verifies efficiency of the algorithm. Practicability of the algorithm is verified in laboratory and the results of comparison on simulation example shows a better effect of channel estimation with the proposed algorithm than standard 2D spread spectrum algorithm and the linear least square algorithm.
