On one hand, this method use link analysis techniques to study hyperlink, calculate the number(More)
Channel estimation is an important technique for OFDM. However, the traditional LMMSE algorithm and SVD algorithm have their own limitations in solving the problem of channel estimation. LMMSE has the highest accuracy, but the computational complexity of the algorithm is very high. Although the SVD algorithm can reduce the complexity of the algorithm, the(More)
