A Comparative Study of Different Modulation Techniques for Wireless Communication Systems
NeuroQuantology · 2023
Wireless communication systems are widely used for communication purposes in various fields such as military, healthcare, transportation, and others.The modulation technique used in these systems plays a vital role in the transmission of data between the transmitter and receiver.In this comparative study, we analyse the performance of different modulation techniques used in wireless communication systems.The four modulation techniques used in this study are amplitude modulation (AM), frequency modulation (FM), phase modulation (PM), and quadrature amplitude modulation (QAM).These techniques differ in the way they modulate the carrier signal, resulting in different signal characteristics and performance metrics.This comparative study shows that each modulation technique has its strengths and weaknesses depending on the specific application requirements.AM is simple and widely used in low data rate applications, while FM and PM are suitable for medium data rate applications.QAM has the highest bandwidth efficiency and is suitable for high data rate applications.The results of this study can help in selecting the appropriate modulation technique for a specific wireless communication system.
