| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Some quantization techniques are used in practice system to reduce the complexity of coding problem. Kurkoski and Yagi proposed an algorithm for finding the optimal quantizer design of channel output for any binary-input discrete memoryless channel in the sense of maximizing mutual information between the channel input and the quantizer output using dynamic programming for a given input distribution. Moreover, Kurkoski, Yamaguchi, and Kobayashi considered a channel input of a finite alphabet but not necessarily binary alphabet, and proposed a suboptimal quantizer design algorithm by using greedy algorithm. In this paper, we evaluate the time complexity and the precision of the algorithm proposed by Kurkoski, Yamaguchi, and Kobayashi. |
