| Abstract(in English) | In Code-Domain NOMA (Non-Orthogonal Multiple Access), the accuracy of MPA (Message Passing Algorithm) detection depends on the employed codebook. In this research, we treat a codebook design problem for code-domain NOMA and propose a power difference codebook for the SCMA (Sparse Code Multiple Access) system. The superiority of the proposed codebook is confirmed by evaluating BLER (Block Error Rate) through computer simulation. |
