Abstract
It discusses the channel estimation algorithm of LS. Because of the complexity of the matrix inversion computation in LS algorithm, we use QR decomposition in LS, that is QRD-LS. Then, the complexity of LS algorithm can be reduced. From the simulation of the LS and QRD-LS algorithm. We can see that the performance of these two algorithm is similary. However, the QRD-LS algorithm has no matrix inversion. So, this algorithm can simplify the calculation.
