New approximations for DQPSK transmission bit error rate [PDF]

open access: yesProceedings of IEEE International Symposium on Applied Computational Intelligence and Informatics, May 23-25, Timi\c{s}oara (2013) 73-77, 2012
In this correspondence our aim is to use some tight lower and upper bounds for the differential quaternary phase shift keying transmission bit error rate in order to deduce accurate approximations for the bit error rate by improving the known results in the literature.

Perception-Based CTU Level Bit Allocation for Intra High Efficiency Video Coding

open access: yesIEEE Access, 2019
The conventional rate control algorithm does not fully consider the characteristics of the Human Visual System (HVS). To address this problem, in this paper, a perception based Coding Tree Unit (CTU) level bit allocation algorithm for intra High ...

Design and Performance Analysis of a New Class of Rate Compatible Serial Concatenated Convolutional Codes [PDF]

open access: yesarXiv, 2005
In this paper, we provide a performance analysis of a new class of serial concatenated convolutional codes (SCCC) where the inner encoder can be punctured beyond the unitary rate. The puncturing of the inner encoder is not limited to inner coded bits, but extended to systematic bits.

Bit error rate calculation for nonlinear interferencecancellation

open access: yesElectronics Letters, 1999
A novel iterative technique for calculating bit error probabilities for direct-sequence code-division multiple-access (DS-CDMA) systems with hard decision successive interference cancellation is proposed. The technique is simple to implement, and gives results close to those obtained by simulations.

Live Recovery of Bit Corruptions in Datacenter Storage Systems [PDF]

open access: yesarXiv, 2018
Due to its high performance and decreasing cost per bit, flash is becoming the main storage medium in datacenters for hot data. However, flash endurance is a perpetual problem, and due to technology trends, subsequent generations of flash devices exhibit progressively shorter lifetimes before they experience uncorrectable bit errors. In this paper we
