Bayesian Bit Error Rate Measurement in MVB Communication

Combining with the signal transmission characteristics of Multifunction Vehicle Bus(MVB),a new evaluating algorithm for BER of MVB was deduced from the posterior distribution model of Bayes.The requirements of confidence limits were fulfilled by this algorithm.Simulation and comparison were proceeded to test the real-time quality of this algorithm.The design schemes of hardware and implementing principle thereof were introduced to expand the BER test function of MVB protocol analyzer.Compared with traditional BER test ways,this algorithm has much better performance in respect of testing-time and accuracy.It is suitable for actual projects to carry out communication quality tests.
