| Abstract: | The design and implementation of the digital baseband part of a DAB transmitter prototype are introduced.It is composed of ensemble multiplexer,channel encoder and OFDM modulator.The equipment is totally compatible with ETS 300 401 and other related standards.It supports services with various data formats and supplies a convenient user interface with the ensemble multiplexer as well.All of its I/O s and the core parts are implemented using modular desig n based on universal int ernal interface,thus can be flexibly configured accordi ng to different demand.Co mpared with the existing products,it can provide highe r flexibility and operating easiness on a much lower cost level. |
