Distance Estimation Based on the Triple-spike Transmission in Diffusion-based Molecular Communication Systems

In recent years, molecular communication (MC) has received much attention as a novel communication paradigm with versatile applications in the biomedical field, nanomaterials, industry and military. The transmission distance is one of the important pa-rameters in MC, and it affects the channel gains, which are important for the detection process in the receiver. The estimation accuracy of distance highly affects the performance and efficiency of the MC system, so an in-depth study is necessary with regard to this issue. Due to the fact that the distance information should be measured and provided before the coherent detection, we propose a novel distance estimation method that requires only one-way transmission without clock synchronization, which is low-complexity and time-saving compared to the previous works.
