| Abstract: | Based on the research of baseband signal demodulation in wireless communication system, this paper realizes the 4QAM modulation and demodulation scheme based on FPGA. Firstly, the basic principles of QAM modulation and demodulation are introduced, and then the design of hardware system and selection of the instruments are presented. Finally and most importantly, the state-machine-based FPGA function module is introduced. The practical measurements show that the system has higher accuracy on the aspect of data transmission and high reliability on the aspect of system operation stability. The scheme has high application value. |
