| Outline of Final Research Achievements |
With the rapid development of communication networks, the analysis of the best attainable performance of a coding system over a wireless communication channel becomes an important research topic. This study aims to analyze the asymptotically optimum coding rate (channel capacity) under the condition that the decoding error probability is upper bounded by a constant for the class of mixed memoryless channel, whose channel law is given by a mixture of multiple stationary memoryless channels. We then discuss a generalization of the obtained results to the multi-user channel, which is a mathematical model of the cognitive radio system. In addition, we investigate related source coding systems and information security.
