Bit error rate prediction of coded MIMO-OFDM systems [PDF]
2008 IEEE 9th Workshop on Signal Processing Advances in Wireless Communications, 2008 Bit error rate (BER) prediction over channel realisations has emerged as an active research area. In this paper, we give analytical signal to interference and noise ratio (SINR) evaluation of MIMO-OFDM systems using an iterative receiver. Using this analytical SINR expression, we propose an accurate BER prediction method based on effective exponential ...

Improvement of Bit Error Rate in Fiber Optic Communications [PDF]
International Journal of Future Computer and Communication, 2014 The bit error rate (BER) is the percentage of bits that have errors relative to the total number of bits received in a transmission. The different modulation techniques scheme is suggested for improvement of BER in fiber optic communications. The developed scheme has been tested on optical fiber systems operating with a non-return-to-zero (NRZ) format ...

A Fast Soft Bit Error Rate Estimation Method
EURASIP Journal on Wireless Communications and Networking, 2010 We have suggested in a previous publication a method to estimate the Bit Error Rate (BER) of a digital communications system instead of using the famous Monte Carlo (MC) simulation.

Ambient Backscatter Systems: Exact Average Bit Error Rate Under Fading Channels [PDF]
IEEE Transactions on Green Communications and Networking, 2018 The success of Internet-of-Things (IoT) paradigm relies on, among other things, developing energy-efficient communication techniques that can enable information exchange among billions of battery-operated IoT devices. With its technological capability of

Bit error rate estimation for turbo decoding [PDF]
IEEE Transactions on Communications, 2003 In this paper we propose a method for on-line estimation of bit error rate during turbo decoding. We model the log-likelihood ratios as a mixture of two Gaussian random variables and derive estimators for the mean and variance of these distributions based on a maximum-likelihood approach. The parameter estimates are then employed to calculate the cross-
