“…VI-B.5 in [59] gives a brief two-paragraph selective overview of channel coding techniques for DBMC. The review articles [60], [61] on reliability and performance enhancing techniques for DBMC include each a one-page overview of channel coding. We also note that an overview of channel coding in DBMC is provided by Damrath in his dissertation [62].…”

Diffusion-based molecular nanonetworks exploit the diffusion of molecules, e.g., in free space or in blood vessels, for the purpose of communication. This article comprehensively surveys coding approaches for communication in diffusion-based molecular nanonetworks. In particular, all three main purposes of coding for communication, namely source coding, channel coding, and network coding, are covered. We organize the survey of the channel coding approaches according to the different channel codes, including linear block codes, convolutional codes, and inter-symbol interference (ISI) mitigation codes. The network coding studies are categorized into duplex network coding, physical-layer network coding, multi-hop nanonetwork coding, performance improvements of network-coded nanosystems, and network coding in mobile nanonetworks. We also present a comprehensive set of future research directions for the still nascent area of coding for diffusion-based molecular nanonetworks; specifically, we outline research imperatives for each of the three main coding purposes, i.e., for source, channel, and network coding, as well as for overarching research goals.

“…This impact is already witnessed in prevailing real-world communication systems that use visible light or free-space optics where synchronisation between the receiver and transmitter is not easily maintained and as a result, these systems suffer from synchronisation errors [1,2]. The concern of synchronisation and its related errors are even found in unconventional fields such as DNA sequencing [3,4] to even more intricate specialisations such as molecular communications [5,6]. The latter has gained popularity in recent years as a potential for data communication in nano and micro systems, where open problems in the field contemplate the effects of synchronisation and memory [5,6].…”

With advancements in telecommunications, data transmission over increasingly harsher channels that produce synchronisation errors is inevitable. Coding schemes for such channels are available through techniques such as the Davey-MacKay watermark coding; however, this is limited to memoryless channel estimates. Memory must be accounted for to ensure a realistic channel approximation -similar to a Finite State Markov Chain or Fritchman Model. A novel code construction and decoder are developed to correct synchronisation errors while considering the channel's correlated memory effects by incorporating ideas from the watermark scheme and memory modelling. Simulation results show that the proposed code construction and decoder rival the first and second-order Davey-MacKay type watermark decoder and even perform slightly better when the inner-channel capacity is higher than 0.9. The proposed system and decoder may prove helpful in fields such as free-space optics and possibly molecular communication, where harsh channels are used for communication.

“…Another aspect that plays a central role in the performance of MC communications is the detection task. Optimal and suboptimal detection methods have been proposed in the literature as addressed in [ 18 ], with some recent innovative approaches as in [ 19 ]. However, the complexity of many of the approaches can be excessive particularly, when one considers the need for instantaneous channel state information which, in the MC channel can be very challenging due to the fast time varying nature.…”

It is envisioned that healthcare systems of the future will be revolutionized with the development and integration of body-centric networks into future generations of communication systems, giving rise to the so-called “Internet of Bio-nano things”. Molecular communications (MC) emerge as the most promising way of transmitting information for in-body communications. One of the biggest challenges is how to minimize the effects of environmental noise and reduce the inter-symbol interference (ISI) which in an MC via diffusion scenario can be very high. To address this problem, channel coding is one of the most promising techniques. In this paper, we study the effects of different channel codes integrated into MC systems. We provide a study of Tomlinson, Cercas, Hughes (TCH) codes as a new attractive approach for the MC environment due to the codeword properties which enable simplified detection. Simulation results show that TCH codes are more effective for these scenarios when compared to other existing alternatives, without introducing too much complexity or processing power into the system. Furthermore, an experimental proof-of-concept macroscale test bed is described, which uses pH as the information carrier, and which demonstrates that the proposed TCH codes can improve the reliability in this type of communication channel.
