代码说明:

应用背景OFDM作为LTE的关键技术之一,应用越来越广泛,这个代码是在DSP上实现OFDM通信系统,很有参考价值关键技术OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术,实际上OFDM是MCM(Multi Carrier Modulation),多载波调制的一种。OFDM技术由MCM(Multi-Carrier Modulation,多载波调制)发展而来。OFDM技术是多载波传输方案的实现方式之一,它的调制和解调是分别基于IFFT和FFT来实现的,是实现复杂度最低、应用最广的一种多载波传输方案。

  • DSK6713在CCS5下 运行工程
    资源描述A workspace folder containing two example projects from the book is supplied in file C6713_CCSv5.zip.The file C6713_CCSv5.zip has deliberately been made quite small, providing just two example projects and not duplicating common support files that are supplied on the CDROM. In order to run example programs from the book using CCSv5, in addition to the file C6713_CCSv5.zip you will need to have access to the files on the CDROM that comes with the book.
