基于System Generator的1024QAM调制解调系统
1 0 2 4QAM modulation and demodulation system based on System Generator
摘要
Abstract
The low order QAM modulation signal is difficult to meet the demand of communication,so an efficient QAM sys-tem is designed.Based on the thought of software radio platform and the algorithms of digital orthogonal,the 1024QAM modem system is set up,the digital frequency conversion and bit synchronization module are designed.System Generator tool is used for modeling and simulation at last.The result shows that the system can recover the original signal correctly, and the transmission rate is up to 10 bit/(s·Hz).The problem of band tension is improved and the better reliability is ob-tained at high signal to noise ratio (≥30 dB)condition.关键词
