| Outline of Final Research Achievements |
In the case that a noiseless feedback channel can be used, the Yamamoto-Itoh (YI) scheme and the Posteriori Matching (PM) scheme can attain high performance for discrete memoryless channels and Gaussian-noise channels, respectively. In this study, the YI scheme is extended to the case of noisy feedback channels, and the YI and PB schemes are extended to the cases of multi-user channels (multi-access channels, broadcast channels, interference channels) with noiseless feedback channels. Furthermore, identification coding for multiple objects are also extended to the case with noiseless feedback channels. For each case, a devised coding scheme is proposed, and the coding theorems are proved to clarify the performance of the proposed schemes.
