The molecules propagation via the molecular communication channel is governed by Fick’s law that describes movement of molecules based on the difference between concentration levels at the transmitter and at the receiver. If the receiver does not absorb all molecules sent, then the molecules stay in the channel influencing future transmission. This leads to accumulation of molecules meaning the channel has memory. The paper deals with developing the detection method for such a cumulative channel. By mapping the received signals and forming a trellis plot we were able to observe the received signal changes and design a detection method based on the trellis. In the paper, we simulate a molecular transmission, including absorption, inter symbol interference and noise, and their respective effects on the transmitted data.

通过分子通讯通道传播的分子受菲克定律控制，该定律根据发射器和接收器浓度水平之间的差异描述分子的运动。如果接收器没有吸收所有发送的分子，则分子会留在通道中，影响以后的传输。这导致分子积聚，意味着通道具有记忆力。本文致力于开发这种累积通道的检测方法。通过映射接收到的信号并形成网格图，我们能够观察到接收信号的变化并设计基于网格的检测方法。在本文中，我们模拟了分子传输，包括吸收，符号间干扰和噪声，以及它们各自对传输数据的影响。
