论文摘要
在移动分子通信（MC）中，符号间干扰（ISI）可以通过功率控制来减轻，需要准确估算从发射器到接收器的距离。我们基于二元浓度偏移键（BCSK），即基于距离（BCSK-D）（BCSK-D）的BCSK以及功率控制的BCSK提出了两种功率控制策略，即BCSK共同考虑通道中的距离和残留分子（BCSK-D-RM）。根据位错误率（BER），每位平均能量消耗以及最佳检测阈值分析BCSK-D和BCSK-D-RM的性能。仿真结果表明，BCSK-D-RM和BCSK-D在BER中的表现优于BCSK，其距离和传输分子的数量。由于BCSK-D-RM的性能较高，而BCSK-D的复杂性较低，因此这些方案对Mobile MC提供了有用的设计权衡。
In mobile molecular communication (MC), inter-symbol interference (ISI) can be mitigated by power control, requiring accurate estimates of the distance from transmitter to receiver. We present two power control strategies based on binary concentration shift keying (BCSK), namely BCSK with power control based on distance (BCSK-d), and BCSK with power control jointly considering distance and residual molecules in the channel (BCSK-d-RM). Performance of BCSK-d and BCSK-d-RM are analyzed in terms of the bit error rate (BER), the average energy consumption per bit, and the optimal detection threshold. Simulation results show that BCSK-d-RM and BCSK-d outperform BCSK in BER with the varying distance and the number of transmitted molecules. As BCSK-d-RM has higher performance, while BCSK-d has lower complexity, these schemes present a useful design tradeoff for mobile MC.
