An Experiment to Assess Bit Error Rate in CAN
نویسندگان
چکیده
An atomic broadcast protocol is a very important building block of any fieldbus based dependable distributed embedded system. Under certain error scenarios native CAN mechanisms do not enforce atomic broadcast and inconsistent message duplicates or omissions may occur. The probability of those error scenarios depend on an important factor, the CAN bit error rate. However, up to our best knowledge, no experimental data on CAN bit error rate is available in the literature, and so the existing work in the field of enforcing atomic broadcast in CAN is based on assumptions. In this paper we describe an experimental setup to measure the CAN bit error rate and we present some early results.

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملOptimum Drill Bit Selection by Using Bit Images and Mathematical Investigation
This study is designed to consider the two important yet often neglected factors, which are factory recommendation and bit features, in optimum bit selection. Image processing techniques have been used to consider the bit features. A mathematical equation, which is derived from a neural network model, is used for drill bit selection to obtain the bit’s maximum penetration rate that corresponds ...

متن کاملHigh-speed All- Optical Time Division Multiplexed Node
In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...
