Journal of Marine Science and Engineering, 2021 Turbulence and absorption of seawater are two important factors affecting the signal transmission quality of underwater optical communication link. Here, we study the channel capacity and bit error rate of an underwater extinction communication link with

Adaptive minimum bit-error-rate filtering [PDF]
IEE Proceedings - Vision, Image, and Signal Processing, 2004 Adaptive filtering has traditionally been developed based on the minimum mean square error (MMSE) principle and has found ever-increasing applications in communications. The paper develops adaptive filtering based on an alternative minimum bit error rate (MBER) criterion for communication applications.

Unconditional Security of Single-Photon Differential Phase Shift Quantum Key Distribution
, 2009 In this Letter, we prove the unconditional security of single-photon differential phase shift quantum key distribution (DPS-QKD) protocol, based on the conversion to an equivalent entanglement-based protocol.

Bit error rate measurement above and below bit rate tracking threshold [PDF]
, 1978 Bit error rate is measured by sending a pseudo-random noise (PRN) code test signal simulating digital data through digital equipment to be tested. An incoming signal representing the response of the equipment being tested, together with any added noise ...

Molecular Oncology, EarlyView.The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

Approximate minimum bit-error rate multiuser detection [PDF]
IEEE GLOBECOM 1998 (Cat. NO. 98CH36250), 2002 The minimum mean-squared-error (MMSE) linear multiuser detector is popular because of its good performance and amenability to adaptive implementation. However, there are circumstances in which the linear detector that minimizes the bit-error rate (BER) can significantly outperform the MMSE detector.

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma
Molecular Oncology, EarlyView.The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

A Generalized Bit Error Rate Evaluation for Index Modulation Based OFDM System
IEEE Access, 2020 Orthogonal frequency division multiplexing (OFDM-IM) is a multicarrier transmission technology that modulates information bits not just onto subcarriers by means of M-ary constellation mapping but also onto selected (active) subcarrier indices ...

Asynchronous Chirp Slope Keying for Underwater Acoustic Communication
Sensors, 2021 We propose an asynchronous acoustic chirp slope keying to map short bit sequences on single or multiple bands without preamble or error correction coding on the physical layer.

Bit error rate reduction by PSO in indoor wireless communication [PDF]
[[abstract]]In this paper, a new ultra wideband (UWB) circular antenna array (UCAA) combining particle swarm optimizer (PSO) to minimize the bit error rate (BER) is proposed.
