| Abstract(in English) | In this paper, we consider the application of wireless autoencoder (WAE) to a model of code generation rules for linear dispersion codes (LDC). LDC is a coding scheme in which the modulation symbols are distributed by a dispersion matrix as much as possible in both the spatial and time domains to achieve high reliability owing to the spatio-temporal diversity effect and high transmission rates owing to the spatial multiplexing effect without compromising signal detection accuracy. Typically, the dispersion matrix is numerically searched using random numbers to obtain a higher discrete-input continuous-output memoryless channel (DCMC) capacity. This method requires a significant amount of time to search for a large dispersion matrix. To solve this problem, this paper proposes to improve search efficiency by configuring WAE, a type of machine learning, as a neural network for generating dispersion matrices. In addition, WAE is introduced for signal constellation generation of modulation symbols as well as dispersion matrix generation to improve signal detection accuracy. |
