Abstract (in Japanese) (See Japanese page) 
(in English) In this study, spectral efficiency is increased by MxN by superimposing MIMO (rank M) in the real space with baseband MIMO using a pseudo propagation path (rank N) set up in the baseband domain. To expand the implementation to 5G, the communication capacity was verified using singular value decomposition for decoding. At the RCS Study Group held in March 2024, a verification of pseudo 4x4 MIMO was reported. In this study, the propagation path characteristic superposition was performed using a convolution operation, and simulation verification was performed.
