摘要:
 在射频识别( Radio Frequency IDentification,RFID)系统中,传输信号在高速远距离传输过程中,受传输环境和突发状况等影响,导致传输信号产生畸变和衰减,解调后的基带信号会产生码间干扰,影响了信号传输质量,并且限制了传输的速度。文中提出了一种适用于RFID系统基带数据传输的自适应FFE-DFE均衡的方法。该方法实现复杂度低,不需要很复杂的电路设计,算法计算速度快。实验结果表明,自适应FFE-DFE均衡方法有效改善了均衡效果,减小了误码率,消除了信号中的码间干扰和噪声,数据传输距离大大延长。
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.
