In this paper, we investigate the setting for initial interpolation vector in our previously reported iterative time-domain compression method of multiple-input multiple-output (MIMO) channel state information (CSI). The iterative MIMO-CSI compression method is based on the time-domain CSI compression with frequency-domain CSI bundling and interpolation for all combinations of transmitter and receiver antennas. How accurately the CSI compression is achieved is largely dependent on the initial setting for the interpolation between CSI of different antenna combinations. In our original work, simple linear interpolation is assumed although it is iteratively updated so that the resultant CSI error due to compression is reduced. In the paper, we propose new generation method of the initial interpolation vector, which reuse the actual frequency-domain CSI variation, in order to take into account the periodical channel variation in frequency domain. The numerical results show that the proposed method can further improve the accuracy of the compressed CSI or enhance the CSI compression capability of the original method. |
