摘要

为解决分子通信中由分子扩散带来的码间干扰（ISI）和背景噪声这2个严峻的挑战，采用4种能抵抗ISI的信号特征表示接收信号的瞬态特性，提出了可靠的不依赖于信道冲激响应（CIR）的非相干分子信号检测算法，并设计了自适应阈值计算方法，且给出了误比特率（BER）理论值。仿真结果显示，在同等计算复杂度下所提方案BER比传统方案BER低，因此在计算能力受限的纳米级分子通信系统中具有广泛的应用前景。

Abstract

To solve the inter-symbol interference (ISI) and background noise challenges of molecular communication via diffusion (MCvD)

four ISI-resistant signal-features were deployed

and a reliable non-coherent signal detection algorithm

which was insensitive to different types of molecular channel impulse response (CIR)

was proposed.Also

an adaptive decision threshold and theoretical bound of bit error rate (BER) were deduced.Simulation results demonstrate a lower BER of the proposed non-coherent scheme compared to the state-of-the-art schemes in the same order of computational complexity

therefore suggesting its potential applications for future nano-scale MC.
