Diffusive molecular communications (DiMC) have recently gained attention as a candidate for nano-to microand macro-scale communications due to its simplicity and energy efficiency. As signal propagation is solely enabled by Brownian motion mechanics, DiMC faces severe inter-symbol interference (ISI), which limits reliable and high data-rate communications. Herein, recent literature on DiMC performance enhancement strategies is surveyed; key research directions are identified. Signaling design and associated design constraints are presented. Classical and novel transceiver designs are reviewed with an emphasis on methods for ISI mitigation and performancecomplexity tradeoffs. Key parameter estimation strategies such as synchronization and channel estimation are considered in conjunction with asynchronous and timing error robust receiver methods. Finally, source and channel coding in the context of DiMC is presented.

“…It is shown therein that SMUX-based molecular MIMO faces high inter-link interference (ILI) in addition to ISI. The ILI is especially severe in SMUX that uses BCSK [52], [53]. To remedy this issue, [53] proposes to introduce time interleaving and avoid simultaneous emissions from the transmitter antennas.…”

Molecular communication (MC) can enable the transfer of information between nanomachines using molecules as the information carrier. In MC systems, multiple receiver nanomachines often co-exist in the same communication channel to serve common or different purposes. However, the analytical channel model for a system with multiple fully absorbing receivers (FARs) does not exist in the literature, which is significantly different from the single FAR system due to the mutual influence of FARs. The analytical channel model is essential in analyzing systems with multiple FARs, including MIMO, SIMO, and cognitive molecular communication systems. In this work, we derive an approximate analytical expression for the hitting probability of a molecule emitted from a point source on each FAR on a diffusion-based MC system with three or more FARs. Using these expressions, we derive the channel model for a SIMO system with a single transmitter and multiple FARs arranged in a uniform circular array (UCA). We then analyze the communication performance of this SIMO system under different cooperative receiver schemes and develop several interesting insights.

“…In MIMO system, there is not only ISI but also ILI in different pairs of transmitters and receivers and as a result the modulation methods need more considerations. [20] proposes a spatial multiplexing mitigation modulation method based on pulse position modulation to mitigate ILI. In [21], a new modulation method for MIMO system called Molecular Space Shift Keying(MSSK) is proposed and it can combat both ISI and ILI effectively.…”

Molecular communication(MC) is a significant technology in the field of nano-biology, which uses molecules as message carriers to transmit information. Diffusion channel model is the most common channel model base on Brownian motion in molecular communication since molecules can diffuse to the destination without the need of extra energy supply. However, the random Brownian motion brings high delay and uncertainty to the communication process and thus modulation methods are required to improve the communication performance. The molecular communication system in the SISO (Single Input Single Output) scenario will be seriously affected by ISI (Inter Symbol Interference). In MIMO(Multi-Input Multi-Output) scenario, since there are multiple transmitters and receivers, in addition to ISI, there will be ILI (Inter Link Interference) as well. At present, most modulations are based on the concentration, type, time and space of molecules and only focus on SISO scenario. In this study, inspired by the MoSK(Molecule Shift Keying) modulation method, we proposed a new joint modulation method for MIMO communication in order to minimize the effect of ISI and ILI. Numerical results show that compared with the current modulation scheme, the proposed scheme allows the MIMO system achieve better BER(Bit error rate) performance and transmission rate.
