Abstract
In this paper, based on wireless signal modulation technology, this paper introduces the more mainstream new modulation techniques, including OFDM, GFDM, and UFMC, in recent years. The second part of the article will introduce the wireless communication modulation techniques, the signal transceiver mechanism, and the principle of each part to realize the three systems. In the third part of the paper, the performance of each system in a noisy environment will be simulated and analyzed using the Matlab platform, including the BER comparison and analysis of different systems under different signal-to-noise ratios. In addition, the development of each modulation technology in recent years and the advantages of each technology will be introduced in this part, based on which the corresponding application scenarios and future development trends are also presented. In the future development of communication technology, each technology will also have its development prospect and expectation.
