Template Aging Phenomenon in Iris Recognition

IEEE Access, 2013
Biometric template aging is defined as an increase in recognition error rate with increased time since enrollment. It is believed that template aging does not occur for iris recognition.

Identification Codes: A Topical Review With Design Guidelines for Practical Systems

IEEE Access, 2023
A wide range of information technology applications require the identification of a particular message or label that represents the identity of an object at a distance, e.g., over a wireless channel.

Expressions for bit error probability [PDF]

Wireless Communications and Mobile Computing, 2007
AbstractThe bit error probability (BEP) for many wireless communications networks can be expressed in the form R = Pr (X2 < X1) where X1 and X2 are independent random variables. Here, a comprehensive collection of formulas is derived for R by assuming the most commonly known models for X1 and X2.

Slotted Aloha With Capture for OWC-Based IoT: Finite Block-Length Performance Analysis

IEEE Access, 2023
In this paper, we analyze the throughput and reliability of an indoor optical wireless communication (OWC)-based Internet of Things (IoT) system based on Slotted ALOHA (SA) where IoT devices exchange data with an access point (AP).

Adaptive minimum bit-error-rate filtering

, 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

Error-bound formulation for multichannel reception of M-DPSK and pilot-aided M-PSK over Rayleigh-fading channels with postdetection combining [PDF]

, 2004
Upper bounds for symbol-error probability are developed for multichannel reception of M-ary phase-shift keying (M-PSK) over frequency-flat Rayleigh-fading channels.

Modelling of Convolutional Structures Focusing on Error Probability Calculation Via Matlab for Safety-Related Applications

Advances in Electrical and Electronic Engineering, 2019
Safety-related communication system SRComS uses a safety code for achieving the integrity of messages transferred between safety-related devices. In most cases, it is a block systematic code that uses syndromic decoding technique. The authors discuss the

Statistical sequential hypotheses testing on para meters of probability distributions of random binary data

Журнал Белорусского государственного университета: Математика, информатика, 2021
An important mathematical problem of computer data analysis – the problem of statistical sequential testing of simple hypotheses on parameters of probability distributions of observed binary data – is considered in the paper. This problem is being solved
