Abstract
Abstract
With the development of digital communication, pulse-position modulation technology has become an important technology in wireless communication due to its efficient bandwidth utilization and sensitive detection efficiency. This study aims to provide some basic information on PPM. In the trend of rapid development of PPM, researchers have found that PPM plays an irreplaceable role, no matter in daily life or scientific research and development. To arouse people’s interest in PPM research, more people are attracted to participate in the study. It began with an introduction to the development process of PPM, and briefly lists the advantages and disadvantages of PPM and the development trend to help readers quickly understand its background knowledge of it. The second part started to work on different modulations based on the previous research on PPM. Various modulation methods are related to each other, and the proposal of each modulation method is based on the shortcomings of existing modulation methods. This study discusses how PPM is used in experiments. Moreover, each experiment’s measurement values and corresponding advantages are analyzed through charts, like Bit Error Rate (BER) and Signal to Noise Ratio (SNR) conducted in each experiment. This study draws a conclusion by discussing the application and the broad horizon for future developments mainly used in communication engineering led by light communication. However, in recent years, PPM has been introduced in many other fields, such as detection and mechanic.
