摘要
为了实现MSK数字调制解调、扩频解扩等复杂算法,设计了以TMS320C6416 DSP和Altera公司FPGAEP3SE110为核心的数字中频调制解调系统,并在此系统中成功实现MSK数字正交调制和MSK复相关解调等复杂运算。该系统的硬件架构,对工程实践数字中频调制解调系统有一定的指导意义。
In order to realize MSK digital modulation and demodulation,spread spectrum and despreading and other complex operations,an information processing circuit of digital IF modulation and demodulation system is successfully developed based on the DSP chip and FPGA EP3SE110,and MSK digital orthogonal modulation and MSK complex related demodulation,and other complex operations is implemented successfully.The hardware structure of digital IF modulation and demodulation system has certain directive significance for engineering practice.
