DARC: HIGH SPEED FM MULTIPLEX BROADCASTING SYSTEM

The DARC (DAta Radio Channel) system is a high speed FM multiplex broadcasting system for mobile reception with a new modulation method called LMSK. It has a transmission capacity of 16 kbit/s, more than 10 times that of the European RDS (Radio Data System). The product code of the code is adopted to correct errors caused by multipath and fading interference. The DARC system is suitable for traffic information services. The broadcasting information includes not only traffic, news, information, and control data for auto-tuning, but also differential global positioning systems and paging data. The information is represented by text, graphics, and data, and these data are multiplexed using a packet data transmission scheme. Steps to standardize the DARC system have been taken. Some commercial FM broadcasters have operated text information services in Japan since 1994. DARC receivers have been developed and are on the market. Introduction of DARC is under consideration in Asia, Europe, and the United States.
