Abstract(in English) | Recently, LDPC (Low Density Parity Check) codes are attracting attention due to the considerable potential for error correction. Generally, an LDPC code is defined by a binary matrix known as a "check matrix". However, the lack of systematic methods of constructing check matrices represents a serious bottleneck to real-world applications. The paper proposes an optimal LDPC code design system that employs stochastic search algorithms and field programmable gate arrays (FPGA). The proposed system is able to identify LDPC codes at high-performance level for error correction and implement them at high-speeds and with a small number of logic elements. Specifically, the system stochastically searches for the optimal codes through a multi-objective optimization technique that enhances selection from among numerous candidates that have trade-off relationships. Moreover, a communication system emulator using FPGAs evaluates each code and determines its performance. This paper describes the proposed system, its structure, and presents the results of an experiment conducted to evaluate its effectiveness. |
