摘要

伪随机二进制编码激励信号越来越多地用于电磁网络分析。各种类型的序列可用于此任务。实际测量需要灵活的高带宽信号发生器。本文提出了一种基于现场可编程门阵列(FPGA)产生芯片频率高达5gchip /s的任意二进制编码信号的概念。此外,还开发了一种快速精确地移动两个编码信号之间的时间滞后的算法,以便在硬件相关器中关联激励和测量信号。首先,比较了两种不同类型的伪随机二值序列,即最大长度序列(MLS)和几乎完全自相关序列(APAS)。然后,给出了FPGA设计,重点介绍了实现两个生成信号之间变时延的算法。最后,给出了一个验证系统的实现和测试结果。

An FPGA-Based Measurement Generator for Cyclically Shifted Binary Signals
Pseudo-random binary coded excitation signals are increasingly used for electromagnetic network analysis. Various types of sequences are available for this task. Flexible signal generators with high bandwidth are required for practical measurements. In this contribution, a concept for the generation of arbitrary binary coded signals with a chip frequency up to 5 Gchip/s based on a field programmable gate array (FPGA) is presented. Furthermore, an algorithm to fast and precisely shift the time lag between two coded signals to allow for correlating excitation and measurement signals in a hardware correlator has been developed. First, two different types of pseudo-random binary sequences, the maximum length sequence (MLS) and the almost perfect autocorrelation sequence (APAS), are compared with each other. Afterwards, the FPGA design with focus on the algorithm to realize a varying time lag between two generated signals is presented. Finally, the realization of a demonstrator system and measurement results for the validation of the system are presented.
