Abstract

China Mobile Multimedia Broadcasting (CMMB) is a self-developed wireless communication system for mobile terminals. The control board is the most important module in CMMB system. This thesis introduces a general modulator control system based on Arm-Linux platform. The platform of the system uses ARM chips as the master controller, by using the Linux embedded platform to achieve the internal among the control panel and baseband coding module, RF output module, RF processing module through the I2C bus, completes dynamic control of the modulator parameters. And LCD display based on Framebuffer, The control system has already been used in the CMMB modular, after testing, the system runs stable and reliable it is very versatility and practical
