This paper consider the problem of obtaining the channel state information (CSI) in downlink massive MU-MIMO systems. As a key technology of future wireless communication, massive MIMO has attracted widespread interest, however, amount of the CSI required became a bottleneck for practical application, especially for FDD transmitting method. In this paper, we propose a novel transmitting scheme, combined...
Baseline correction is an key step in signal pretreatment. The result influences the processing of the next step directly, so it has important actual meaning to find out a method which is simply and available. In this article, we propose an baseline correction method which is based on least square method. Through a great deal of experiment, we prove that the method we propose is a kind of fast, available...
