Research and Implement of DRM Baseband Encoder and Modulator Based on Embedded System

DRM technology has been widely used in modern Digital AM Broadcasting. The design of DRM base band encoder and modulator based on embedded system is presented in order to realize less cost, smaller power loss and more portability for the DRM transmission system. The function of software modules are described in details combined with DRM standard, and relevant solutions are also presented for reference. Finally, the application of this base band encoder and modulator is analyzed.
