Spread spectrum is a technique used for transmitting telecommunications signals. This topic is relatively complex and can be challenging for students. Thus, programming language Octave has been introduced in the course curriculum of Telecommunication Systems as one of the powerful tools that aid in student understanding of the spread‐spectrum principles. The purpose of this paper is to elaborate on the teaching method of spread‐spectrum technique and its application in telecommunications, with the aim to make this topic understandable to students. The participants of the experiment were fifth‐semester electrical engineering students (N = 86) at a college of applied sciences. To test the previous knowledge of students needed to understand the theory of spread spectrum, a pretest was carried out which refers to general terms from the fundamentals of telecommunications. With the aim to deeper apprehend the necessary theory from this area, the students had to solve examples from engineering practice using open source software Octave, as well as computational tasks, regarding both methods in spread‐spectrum technology. It has been shown that thanks to the visualization of appropriate material, students of the experimental group understood in more detail the method of generating spread‐spectrum signals and the influence of individual parameters on partial signals, in relation to students who did not have the opportunity to use Octave. The results of the research lead us to conclude that software like Octave should be included in courses like Telecommunication Systems as a supplement to the traditional teaching and learning methods.

在使用 Octave 的电信系统课程中教授扩频

扩频是一种用于传输电信信号的技术。这个话题相对复杂，对学生来说可能具有挑战性。因此，在电信系统课程中引入了编程语言 Octave 作为帮助学生理解扩频原理的强大工具之一。本文的目的是阐述扩频技术的教学方法及其在电信中的应用，旨在使学生能够理解这一课题。实验的参与者是应用科学学院第五学期的电气工程专业学生（N = 86）。为考查学生之前了解扩频理论所需的知识，进行了一项预测试，其中涉及电信基础的一般术语。为了更深入地理解该领域的必要理论，学生们必须使用开源软件 Octave 解决工程实践中的示例，以及关于扩频技术中的两种方法的计算任务。已经表明，由于适当材料的可视化，与没有机会的学生相比，实验组的学生更详细地了解了生成扩频信号的方法以及单个参数对部分信号的影响使用八度。
