一种应用于RFID数据传输的自适应均衡方法
An Adaptive Equalization Method for RFID Data Transmission
摘要
Abstract
In the process of high speed and long-distance transmission of the RFID system,the signal can be affected by transmission en-vironment and other unexpected effects. These factors can cause distortion and attenuation,the serious Inter-Symbol Interference ( ISI) is produced to the demodulated baseband signal. Then the quality of transmission is affected and the transmission speed is limited. In this pa-per,a method for baseband data transmission of RFID system with an adaptive FFE-DFE equalization is presented. This method has low complexity and does not need complex circuit design,and the algorithm calculates quickly. The experiment results show that the adaptive FFE-DFE equalization method can improve the performance of equalization and reduce the bit error rate. The inter-symbol interference and noise of the signal are also eliminated. The data transmission distance is greatly extended.关键词
