Abstract
Molecular communications are the bio-communication system inspired by nature to convey information in nanoscale networks. The transmitter and receiver can be manufactured from biological materials, hybrid materials, or entirely artificial materials to perform simple tasks such as sensing and counting. The channel impulse response of the diffusion-based propagation channel has a long tail as a result of delayed residual molecules that hit the receiver. Those molecules generate intersymbol interference (ISI) between symbols which harshly-distorted the received signals and complicate detection process. Furthermore, molecular communications always have low throughput measurements due to the presence of ISI. In this paper, we proposed a channel equalization technique that uses only three taps FIR zero-forcing approach to mitigate the ISI. The performance of our equalizer shows remarkable BER and throughput improvement compared to no equalization.
