Channel Estimation Method and System for Massive MIMO Based on Circulant Jacket Matrices

摘要

Provided is a channel estimation method and system for massive MIMO based on a circulant jacket matrices (CJM). According to an embodiment of the present invention, a signal reception channel is estimated based on the circulant matrix. In particular, channel estimation based on the CJM is possible in the massive MIMO, thereby securing a much better communications performance than an existing channel estimation method.
