摘要
当前虽然数字通信技术占据了主导地位,但FM波形在一些特殊的场合仍有较广泛的应用,而工程实现时出现了无专用芯片支持的情况,论文据此提出了一种基于软件无线思想和FPGA硬件平台的FM调制解调器的实现方案。对FM调制解调器的工作原理、硬件平台的设计和软件算法的设计进行了详细的描述,并结合工程实际进行了算法性能仿真分析,仿真结果表明该方案有性能好、消耗资源少、简单灵活的特点,可以替代传统的专用芯片,应用于一些特殊专用的标准和非标准的FM调制解调的场合。
Although the digital communicate technology take up the dominant in present, FM wave still has extensive application at some special occasion, but it has the problem of no appropriative chip support in the proiect realization. In this case this paper puts forward a realize scheme of FM modulate and demodulate base software radio and the FPGA hardware. And description the principle of FM modulate and demodulate are introduced, The design of the hardware and the software arithmetic detailed, simulate and analyze the arithmetic per- formance combine the engine practice, the simulation result show that this scheme has the characteristic of the good pertformance, use the lit- tle resources sacrifice, simple and flexible, can replace the traditional appropriative chip, applicable in same special standard and no--standard FM modulate and demodulate occasion.
