We propose a method by which two radio frequency (RF) communication terminals exchange encryption keys or other data securely. This method draws on the approach developed for quantum key distribution (QKD) for detecting eavesdroppers but our method does not use any quantum properties at all. Instead, by exploiting the…

The Viterbi algorithm, presented in 1967, allows a maximum likelihood decoding of partial response codes. This study focuses on the duobinary code which is the first member of this family and has been specified for the digital part of television systems recommended by International Organizations. Up to now the…

One of the key advantages of terahertz (THz) communication is its potential for energy efficiency, making it an attractive option for green communication systems. Coherent THz transmission technology has recently been explored in the literature. However, there exist few error performance results for such a wireless…

As nanopore technology reaches ever higher throughput and accuracy, it becomes an increasingly viable candidate for reading out DNA data storage. Nanopore sequencing offers considerable flexibility by allowing long reads, real-time signal analysis, and the ability to read both DNA and RNA. We need flexible and…

Thermodynamic cost of communication is a major factor in the thermodynamic cost of real-world computers, both biological and digital. However, little is known about the fundamental features of this cost. Addressing this hole in the literature, our first major contribution is a strictly positive lower bound on on the…

Mobile multimedia communication requires considerable resources such as bandwidth and efficiency to support Quality-of-Service (QoS) and user Quality-of-Experience (QoE). To increase the available bandwidth, 5G network designers have incorporated Cognitive Radio (CR), which can adjust communication parameters according…

'Bane Vasic' 'Syed A. Jafar'] We examine the effects of imperfect phase estimation of a reference signal on the bit error rate and mutual information over a communication channel influenced by fading and thermal noise. The Two-Wave Diffuse-Power (TWDP) model is utilized for statistical characterization of propagation…

—Using a generating function approach, a computationally tractable expression is derived to predict the frame error rate arising at the output of the binary symmetric channel when a number of outer Reed–Solomon codes are concatenated with a number of inner Bose–Ray-Chaudhuri–Hocquenghem codes, thereby obviating the…

Concatenated codes with Reed–Solomon (RS) outer codes and Bose–Ray-Chaudhuri–Hocquenghem (BCH) inner codes are attractive for high-throughput communication systems, such as data centre interconnects, that require low complexity and low latency [1, 2]. Such coding schemes are often used in conjunction with four-level…

'Miroslav Voznak' 'Mohammed Balfaqih'] Short-packet communication (SPC) is a key enabler for ultra-reliable low-latency communication (URLLC) in next-generation wireless networks. In this paper, we investigate the block error rate (BLER) performance of a reconfigurable intelligent surface (RIS)-assisted ambient…

—This paper investigates two distinct types of block errors – undetected errors (confusions) and erasures – in additive white Gaussian noise (AWGN) channels with error-bounded block decoders operating in the finite blocklength (FBL) regime. While block error rate (BLER) is a common metric, it does not distinguish…

Efficient error-correction codes are crucial for realizing DNA’s potential as a long-lasting, high-density storage medium for digital data. At the same time, new workflows promising low-cost, resilient DNA data storage are challenging their design and error-correcting capabilities. This study characterizes the errors…

This paper presents an approach to error correction in wireless communication systems, with a focus on the Bluetooth Low Energy standard. Our method uses the redundancy provided by the cyclic redundancy check and leaves the transmitter unchanged. The approach has two components: an error-detection algorithm that…

Copying information is vital for life's propagation. Current life forms maintain a low error rate in replication using complex machinery to prevent and correct errors. However, primitive life had to deal with higher error rates, limiting its ability to evolve. Discovering mechanisms to reduce errors would alleviate…

—Zipper codes with irregular variable degree are studied. Two new interleaver maps—chevron and half-chevron are described. Simulation results with shortened double-errorcorrecting Bose–Chaudhuri–Hocquenghem constituent codes show that zipper codes with chevron and half-chevron interleaver maps outperform staircase…

Signaling pathways transmit and process information, enabling cells to respond accurately to external cues. Disease states like cancer can corrupt signal transmission, though the magnitude to which they reduce information capacity has not been quantified. Here we apply pseudo-random pulsatile optogenetic stimulation…

The polymerase chain reaction (PCR) is a central technique in biotechnology. Its ability to amplify a specific target region of a DNA sequence has led to prominent applications, including virus tests, DNA sequencing, genotyping, and genome cloning. These applications rely on the specificity of the primer hybridization…

In this paper, we propose a DNA storage encoding scheme based on a 64-element coding table combined with forward error correction. The method encodes the data into DNA sequences by LZW compression of the original text, adding error correction codes and scrambling codes. In the encoding process, the effects of GC…

—In this paper, a technique for the Berlekamp-Massey(BM) algorithm is provided to reduce the latency of decoding and save decoding power by early termination or earlystopped checking. We investigate the consecutive zero discrepancies during the decoding iteration and decide to early stop the decoding process. This…

While our senses transmit information at rates exceeding 10^6^ bit/s, high-level cognitive processing is thought to be much slower, on the order of 10 bit/s regardless of the task^1^. It is unclear, though, whether this limit holds when the human mind is challenged. To test how fast one can process abstract…

As anyone who has tried to memorize a one-hundred-digit number can attest, acquisition of numerical information typically proceeds at less than one bit/s. If human memory operated at this speed in general, even a simple conversation would not be possible. Indeed, through techniques such as the memory palace, which…
