本文介绍了一种基于二进制序列的时域信道探测器。通道探测器系统由几个现成的实验室仪器组成，并由PC控制。感兴趣的频带是未经许可的毫米波段，57-64 GHz。所提出的系统的一个重要特点是其快速的测量速度，使现实的车辆场景的测量。研究的主要部分是专门的描述和分析的系统行为时，非线性元件，如混频器，低噪声放大器或功率放大器的使用。本研究的贡献是如何减轻这些影响，利用几种不同的激励信号的描述和评估和比较的信道探测器的性能方面的无杂散动态范围参数。
This study describes a time domain channel sounder based on binary sequences. The channel sounder system consists of several off-the-shelf laboratory instruments and is controlled by a PC. The frequency band of interest is the unlicensed millimetre wave band, 57–64 GHz. A crucial feature of the proposed system is its fast measurement speed enabling measurements of realistic vehicular scenarios. The main part of the study is dedicated to the description and analysis of the system behaviour when nonlinear components, such as mixers, low noise amplifiers or power amplifiers are used. The contributions of this study are the description of how to mitigate these effects utilising several different excitation signals and the evaluation and comparison of the channel sounder performance in terms of the spurious-free dynamic range parameter.
