Bit error rate test accessory makes errors audible
Review of Scientific Instruments, 2001A simple accessory for bit error rate test instruments provides a means to monitor error rate audibly without watching a display so that the user may observe and make adjustments to equipment under test while hearing the effects of these adjustments. Normally inaudible narrow error pulses trigger a toggle flip-flop to provide a signal rich in audible ...

Block-Shanno Minimum Bit Error Rate Beamforming
IEEE Transactions on Vehicular Technology, 2008Beamforming is a key technology in smart antenna systems that can increase capacity and coverage and mitigate multipath propagation in mobile radio communication systems. The most popular criterion for linear beamforming is the minimum mean square error (MMSE).

Jitter Effects on Bit Error Rate Reexamined
IEEE Transactions on Communications, 1981Standard 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 ...

Class of Minimum Bit Error Rate Algorithms
The 9th International Conference on Advanced Communication Technology, 2007A class of adaptive beamforming algorithms was proposed based on directly minimizing the bit-error rate (BER). The popular linear minimum bit error rate (MBER) stochastic beamforming algorithms suffer from low convergence speed and large training data.

Bit error rate in digital azimuth recording
IEEE Transactions on Magnetics, 1987Azimuth recording can reduce the side reading and thus allow a playback head wider than the track pitch to obtain a large tracking margin. Since the azimuth rejection is usually poor at long wavelength, it is preferred to employ a dc-free code to roll-off the long wavelength spectrum.

Bit error rate in NAND Flash memories
2008 IEEE International Reliability Physics Symposium, 2008NAND flash memories have bit errors that are corrected by error-correction codes (ECC). We present raw error data from multi-level-cell devices from four manufacturers, identify the root-cause mechanisms, and estimate the resulting uncorrectable bit error rates (UBER). Write, retention, and read-disturb errors all contribute.

Bit error rate performance of coded 8PSK
16th International Communications Satellite Systems Conference, 1996This paper presents the coded BERs of low-sideband (LSB)-coded 8PSK and a semianalytic technique for computing the BERs of LSB-encoded 8PSK. The uncoded MSB, 2SB, and LSB BERs are presented, and then LSB error-correction coding is applied, and the BERs of the coded MSB, 2SB, and LSB are found.

Convolutional Encoders to Minimize Bit‐Error‐Rate
European Transactions on Telecommunications, 2000AbstractThe 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.
