Jitter Effects on Bit Error Rate Reexamined

IEEE Transactions on Communications, 1981
Standard references show the effects of carrier phase jitter on the performance of digital communications equipment as curves of bit error rate versus signal-to-noise ratio for constant values of jitter variance. In any real system, the variance consists of a relatively small constant component and a component which is inversely proportional to signal ...

Sequential Bayesian Bit Error Rate Measurement

IEEE Transactions on Instrumentation and Measurement, 2004
As bit error rates decrease, the time required to measure a bit error rate (BER) or perform a BER test (i.e., to determine that a particular communications device's BER is less than some acceptable limit) increases dramatically. One cause of long measurement times is the difficulty of deciding a priori how many bits to measure to establish the BER to ...

Convolutional Encoders to Minimize Bit‐Error‐Rate

European Transactions on Telecommunications, 2000
AbstractThe results of a computer search for convolutional encoders for the binary symmetric channel and the additive white Gaussian noise channel are reported. Both feed‐forward and feedback encoders are considered. It is shown that, when bit error rate is the design criterion.

Bit Error Rates

2001
A practical consideration that has so far received little attention is the correcting power of the coding required to do the job. In other words, if we need a certain improvement in channel performance, how many bits must we be able to correct? This aspect of the subject gets quite mathematical, so I shall give only a simplified view of the problem in ...

On Monte Carlo Simulation of the Bit Error Rate

2011 IEEE International Conference on Communications (ICC), 2011
Simulation, point estimation, and interval estimation of the bit error rate are rigorously examined. Exact confidence intervals based on the F-distribution approximation for the binomial and negative binomial distributions are derived. Simulations demonstrate 1) that the analysis gives accurate confidence intervals for bit error rate estimators and 2 ...

Bit error probabilities in a two-rate communication system

IEEE International Conference on Communications, 2003. ICC '03., 2004
We examine a two-rate communication system where the transmission is suspended if the received SNR falls below a given threshold. We assume an FDD system and derive novel closed-form bit error probabilities in the presence of feedback errors in flat Rayleigh fading environment for single antenna transmission, orthogonal space-time block coding and ...

Determining the Bit Error Rate for Redundant Transmission

2016
In this article a bit error rate for redundant transmission is determined. The method is based on the error rate of received bitstream for different levels of redundancy and does not require any information about transmission channel and original data. The main goal was to derive a simple closed form expression that leads to good performance and makes ...

On the minimum bit-error rate of linear codes

IEEE Transactions on Information Theory, 1995
Summary: We investigate the bit-error rate (BER) of linear block codes. The BER is a function of the encoder realization of the code. We express the BER in terms of the weight profiles of the subspaces of the code. We also discuss the relation between the Hadamard transform and the BER.

Improved bit error rate performance of convolutional codes with synchronization errors

2015 IEEE International Conference on Communications (ICC), 2015
A maximum a posteriori decoder is given for convolutional codes when transmitted over a binary random error channel that exhibits insertion, deletion and substitution errors. It is shown that the error-correcting performance of these codes can be improved by more than two orders of magnitude when compared to similar systems found in the literature, for

Bit error rate estimation for channels with memory

IEEE Transactions on Communications, 1988
A method for deriving key parameters of a bit-error-rate (BER) estimate is presented. The method is based on a bursty channel model proposed by B.D. Fritchman (IEEE Trans. Inform. Theory, Vol. IT-13, pp.221-227, Apr. 1967). This model is used to derive the confidence levels and confidence intervals of an error-rate estimate.
