The Design Of OFDM In Embeded System

Along with the development of electron technic and network, interlink and wireless communication will be the trend of embedded system development.The widely used 32-bit embedded CPU not only satisfies the need of high-speed processing, but also provides a platform which makes the embedded operating system run steadily, speedily and credibly. Operating system is the weight-bearing point in fields of Embedded system, and greatly accelerates the software development and enhances the system's stability and security. As the advantage of price, open and rich resource, tiny kernel, Linux has been widely used in embedded system.OFDM(Orthogonal Frequency Division Multiplexing) is a multi-carrier data modulation technology. With the development in DSP chip technology, and the import of 64/128/256QAM technology in fourier transform/inversion and high-speed modem, people are devoting more and more vigor in developing the application of OFDM in wireless communication.
