论文摘要
在分子通信（MC）中，在发射机处将不同类型的颗粒结合在一起是一种自由度，可用于提高性能。在本文中，我们通过利用和组合不同大小颗粒的接收信号特征来解决脉冲成型的问题，以简化时间同步要求。特别是，我们优化了用于传输的不同尺寸的颗粒的混合物，以支持开关键合的规定检测时间段，平均保证1）如果二进制的信号是足够大的接收信号，如果二进制传输二进制的信号，则如果传输二进制的信号，则如果二进制零是在隔离板间间隔内传输的足够低的信号。为了进行说明，我们考虑了基于自由空间扩散通道模型的优化问题。结果表明，不同粒径的最大可行检测持续时间与最小粒径的峰值检测值之间的权衡，这使最大的检测持续时间到最大的粒径最小化峰值检测值以有限检测持续时间为代价。
In molecular communication (MC), combining different types of particles at the transmitter is a degree of freedom which can be utilized to improve performance. In this paper, we address the problem of pulse shaping to simplify time synchronization requirements by exploiting and combining the received signal characteristics of particles of different sizes. In particular, we optimize the mixture of particles of different sizes used for transmission in order to support a prescribed detection time period for on-off keying, guaranteeing on average 1) a sufficiently large received signal if a binary one is transmitted, and 2) a low enough received signal if a binary zero is transmitted even in the presence of inter-symbol interference. For illustration, we consider an optimization problem based on a free space diffusion channel model. It is shown that there is a tradeoff between the maximum feasible detection duration and the peak detection value for different particle sizes from the smallest particle size enabling the largest detection duration to the largest particle size minimizing the peak detection value at the expense of a limited detection duration.
