This paper proposes a power domain superposition modulation method based on dimensional level transformation and five dimensions (5D) constellation shaping. Stacking a regular triangular pyramid and enhancing it in terms of dimensions achieves the geometric shaping of the 5D constellation. Based on this, signal superposition in the power domain is achieved through dimensional transformation for data modulation. Experimental verification was conducted on a 2 km seven-core fiber in an IM/DD system.
