Capacity of uncoordinated multiple access channel (MAC) with single-user demodulation has been studied in literature under various assumptions for symbol-synchronous transmission. This paper considers symbol-asynchronous uncoordinated transmission on a binary continuous-time noiseless MAC. It first proposes and develops a new multi-user interference analysis approach that in turn allows exact evaluation of the mutual information on the multi-access channel. Consequently, the sum-capacity of the considered binary symbol-asynchronous uncoordinated MAC is determined.

符号异步多路访问信道上的信息速率

容量 不协调 在各种假设下，文献中已经研究了具有单用户解调的多路访问信道（MAC）。 符号同步传播。本文认为符号异步二进制连续时间无噪声MAC上的非协调传输。它首先提出并开发了一种新的多用户干扰分析方法，从而可以对多址信道上的互信息进行精确评估。因此，确定了所考虑的二进制符号异步非协调MAC的总容量。
