“…time complexity of three types of interleaving methods. These are row interleaving, block interleaving, and no-interleaving, expressed as O(4mn), O(4mn − 4m + 4) [26], and O(2mn), respectively. Although the no-interleaved has the lowest time complexity, it is less effective at correcting burst errors caused by the back-stepping motion of molecular hoppers.…”

DNA-based molecular communication (DNA-MC) is a biological communication mechanism that uses DNA strands as information carriers. The longevity, stability, high information density, massive parallelism, and biological compatibility of DNA offer a dramatic potential for DNA-based storage, computing, and communication. This paper extends our previous work, which used the directional and controllable molecular hopper along the track to replace the slow and random diffusion mechanisms. This paper proposes a multiple-track-hopper parallel communication mechanism to achieve high throughput by parallel transmission and sequencing. We recommend utilizing interleaved coding to mitigate the bit error rate (BER) caused by the back-stepping motion, resulting in successive symmetric errors. Additionally, we have explored the proper interleaving depth necessary to preserve the diminished DNA information density that results from the redundancy for error correction. Simulations show that interleaved coding efficiently reduces BER in parallel DNA-MC while requiring less redundancy. This paper demonstrates the feasibility and potential of high-throughput and low-error DNA-MC, which could enable novel interdisciplinary advances between DNA communication, nanotechnology, and synthetic biology.

Turbo code is an error correction coding scheme close to the Shannon limit, usually used in wireless data transmission. Based on the parallel Turbo code algorithm, a parallel Turbo code circuit design scheme is proposed. In the encoder, the recursive systematic convolutional encoder is multiplexed. The decoder is divided into branch metric, recursive, maximum likelihood ratio, and external information calculation modules. The decoding algorithm is based on Max-Log-MAP, controlling the component decoder in parallel. And the state metric calculation in the decoding circuit is combined to reduce the overall power consumption effectively, enabling the encoder and decoder to be used in narrowband Internet of things (NB-IoT). Finally, the hardware scheme of the main functional modules of Turbo code encoding and decoding is designed and implemented. The results show that the dynamic power consumption is less than 50 mW. The overall on-chip power consumption is reduced by 40% at the frequency of 125 MHz compared with previous jobs.
