论文摘要
考虑了一维（1-D）异常 - 扩散分子通信通道，其中设备（发射器（TX）和接收器（RX））可以沿轴沿任一方向移动。为了建模携带分子（ICM）以及TX和RX的异常扩散，探索了时间缩放的布朗运动的概念。在这种情况下，得出了首次击打时间密度（FHTD）的新型闭合表达。此外，通过基于粒子的模拟验证了派生的FHTD。对于二进制信息的传输，将利用定时调制。此外，该通道被假定为二元擦除通道（BEC），并根据可实现的信息率（AIR）进行分析。
A one-dimensional (1-D) anomalous-diffusive molecular communication channel is considered, wherein the devices (transmitter (TX) and receiver (RX)) can move in either direction along the axis. For modeling the anomalous diffusion of information carrying molecules (ICM) as well as that of the TX and RX, the concept of time-scaled Brownian motion is explored. In this context, a novel closed-form expression for the first hitting time density (FHTD) is derived. Further, the derived FHTD is validated through particle-based simulation. For the transmission of binary information, the timing modulation is exploited. Furthermore, the channel is assumed as a binary erasure channel (BEC) and analyzed in terms of achievable information rate (AIR).
