The future of digital radio could take the shape of a China Digital Radio system targeting the switch from analogue FM to digital radio in the country.

The Chinese Academy of Broadcasting Science and State Administration of Radio, Film, and Television (SARFT) is demonstrating research suggesting the system is better than current DAB, DRM (Digital Radio Mondiale) and HD radio systems.

The invention uses LDPC code as its FEM scheme to provide 2-3 dB of code gain over convolutional code in DAB/DRM/HD radio systems.

This IBC is the first showing of the CDR system outside China. Exhibits on its Future Zone booth include audio encoder, multiplexer, exciter, receiver and the chip.
