摘要
软件无线电的思想已推广到无线电通信领域,该技术依托于宽频段、特性均匀的天线,高速的AD/DA芯片,可编程大规模逻辑门阵列,通用高速的DSP数字信号处理芯片等硬件技术。介绍了AM调制和解调的数字化实现方法,给出了基于TMS320C32DSP芯片实现AM调制解调算法的主要源程序。经测试,该软件设计在软件无线电硬件平台上运行良好,整个系统的各项性能指标均达到设计的要求。
The thought of the software wireless has already expanded into wireless correspondence realm. That technique depends on hardware technique of wide band and even antenna,high speed AD/DA chip,an array of programmable large -scale logic,the high speed DSP numerical signal processing chip, And realization of AM modulation and demodulation are introduced, the main programming of AM modulation and demodulation algorithm based on TMS320C32DSP chip is given. Through the test that software desizn revolves on the software radio hardware platform,various function index signs of system all attain the request of design,
