Bit Error Rate Analysis for Reconfigurable Intelligent Surfaces With Phase Errors [PDF]

open access: yesIEEE Communications Letters, 2021
In this paper, we analyze the error probability of reconfigurable intelligent surfaces (RIS)-enabled communication systems with quantized channel phase compensation over Rayleigh fading channels. The probability density and characteristic functions of the received signal amplitude are derive dand used to compute exact expressions for the bit error rate(

Bit Error Rate for NOMA Network

open access: yesIEEE Communications Letters, 2020
This letter examines the bit error rate (BER) performance of downlink non-orthogonal multiple access networks for binary phase-shift keying modulation. Exact BER expression is derived for each user in closed-form under additive white Gaussian noise and Rayleigh fading channels in perfect and imperfect successive interference cancellation (SIC) cases ...

Capacity Versus Bit Error Rate Trade-Off in the DVB-S2 Forward Link [PDF]

open access: goldEURASIP Journal on Wireless Communications and Networking, 2007
The paper presents an approach to optimize the use of satellite capacity in DVB-S2 forward links. By reducing the so-called safety margins, in the adaptive coding and modulation technique, it is possible to increase the spectral efficiency at expenses of

Bit Error Rate is Convex at High SNR [PDF]

open access: yesarXiv, 2009
Motivated by a wide-spread use of convex optimization techniques, convexity properties of bit error rate of the maximum likelihood detector operating in the AWGN channel are studied for arbitrary constellations and bit mappings, which may also include coding under maximum-likelihood decoding.

Adaptive minimum bit-error rate beamforming [PDF]

open access: greenIEEE Transactions on Wireless Communications, 2005
An adaptive beamforming technique is proposed based on directly minimizing the bit-error rate (BER). It is demonstrated that this minimum BER (MBER) approach utilizes the antenna array elements more intelligently than the standard minimum mean square error (MMSE) approach.

Quantum bit error rate in modeled atmospheres [PDF]

open access: greenInternational Journal of Quantum Information, 2008
The quantum bit error rate is a key quantity in quantum communications. If the quantum channel is the atmosphere, the information is usually encoded in the polarization of a photon. A link budget is required, which takes into account the depolarization of the photon after its interaction with the atmosphere as well as absorption, scattering and ...

Time Domain Equalizer Design Using Bit Error Rate Minimization for UWB Systems [PDF]

open access: goldEURASIP Journal on Wireless Communications and Networking, 2009
Ultra-wideband (UWB) communication systems occupy huge bandwidths with very low power spectral densities. This feature makes the UWB channels highly rich in resolvable multipaths.

The Influence of Signal Polarization on Quantum Bit Error Rate for Subcarrier Wave Quantum Key Distribution Protocol [PDF]

open access: yesEntropy, 2020
In this paper, we consider the influence of a divergence of polarization of a quantum signal transmitted through an optical fiber channel on the quantum bit error rate of the subcarrier wave quantum key distribution protocol.

On the bit error rate of repeated error-correcting codes [PDF]

open access: green2014 48th Annual Conference on Information Sciences and Systems (CISS), 2014
Classically, error-correcting codes are studied with respect to performance metrics such as minimum distance (combinatorial) or probability of bit/block error over a given stochastic channel. In this paper, a different metric is considered. It is assumed that the block code is used to repeatedly encode user data.
