First, there are two problems in applying ICA to MIMO.
The first is that the amount of arithmetic operations required to derive a large MIMO channel matrix becomes large.
The second is that a long data series is required to evaluate the non-Gaussianity of signals by ICA.
Therefore, we propose a method.
It is to improve the accuracy of ICA by applying independent component analysis to MIMO for signal detection and applying deep expansion to ICA to evaluate non-Gaussianity even with a short data series. |
