| 摘 要： | 为了减少集成电路硬件复杂度，针对QAM调制软件实现速度慢的问题，在分析MQAM调制原理的基础上，采用直接频率合成实现正余弦信号及无时延改进的滤波器编程方法，提出一种快速实现MQAM调制算法的软件编程思想，并以TMS320C55X为平台，将MQAM调制算法进行了C编程实现。结果表明：该编程方法能快速产生MQAM调制信号。

| Abstract: | In order to reduce the complexity of integrated circuit, aiming at the low speed of QAMmodulation software, a software-programming idea for rapidly implementing MQAM modulation algorithm is proposed, which uses direct digital synthesis for realizing sine and cosine signals and filter-programming method without delay improvement. And a C program on MQAM is implemented with TMS3320C5502 as the platform. The experiment results indicate that the programming method can rapidly produce MQAM modulating signal. |
