Study on Digital Radio Mondiale Signal Monitor System for Wireless Communication Security

To meet the need of signal acquisition for Digital Radio Mondiale (DRM) equipment in communication security application, an embedded system is set up by combing signal acquisition and decoding module, host computer monitor module and PC104 bus control module, taking advantage of high data transmission efficiency on PC104 bus. Signal data is acquired and decoded by signal acquisition and decoding module. Data transmission between embedded CPU and host computer CPU is completed by PC104 bus control module. Finally the signal data is displayed on host computer monitor module. Application result shows that the system is easy to operate. It has broad application prospects in DRM communication security technology.
