Abstract

In this paper are presented the results regarding the implementation of a reliable encoder that is intended to be used in automotive applications for accurately transferring digital signals from different types of sensors, control elements and other peripheral components to a central processing unit. The designed module is capable to operate with various line coding schemes such are: NRZ (non-return-to-zero), RZ (return-to-zero), AMI (alternate mark inversion) and Manchester (phase encoding). During extensive simulations and practical measurements it was revealed that the maximum data communication speed achieved by the designed system is around 1 Mb/s, when the signal-to-noise ratio is maintained above 10 dB. The enhanced implementation of the proposed encoder, based on synchronized line-codes, offers good performances regarding the resistance to perturbations as well as an improved spectral shaping and clock recovering capabilities for obtaining efficient internal data transmission systems for vehicles.

汽车用串行数据传输线路编码器

本文介绍了一种可靠编码器的实现结果，该编码器旨在用于汽车应用，用于准确地将来自不同类型的传感器、控制元件和其他外围组件的数字信号传输到中央处理单元。所设计的模块能够使用各种线路编码方案，如:NRZ(不归零)，RZ(归零)，AMI(交替标记反转)和Manchester(相位编码)。通过大量的仿真和实际测量表明，当信噪比保持在10 dB以上时，所设计的系统实现的最大数据通信速度约为1 Mb/s。基于同步线码的编码器的增强实现，在抗扰动方面提供了良好的性能，以及改进的频谱整形和时钟恢复能力，可以为车辆获得高效的内部数据传输系统。
