  • Page 54: Explanation

    GEX-P900DAB 7.3 EXPLANATION 7.3.1 CIRCUIT DESCRIPTION - What is DAB? Digital Audio Broadcasting (DAB) is digital broadcasting for mobile communications using the MUSICAM (MPEG Audio) audio compression system. The system was developed by the EUREKA 147 in Europe. For the digital modula- tion system, DAB uses Coded Orthogonal Frequency Division Multiplex (COFDM) based on multicarrier.
  • Page 55 GEX-P900DAB - Why DAB is More Effective with Multipath Than FM? Different from FM, DAB systems are designed under the conditions that multipath exists. DAB disperses the portion that will be distorted by multipath, and corrects such part with error correction.
  • Page 56 GEX-P900DAB 3) Guard interval The time 25% more than the sampling time required for processing DAB signals by FFT is called "guard interval." For multipath within the time of guard interval, errors can be corrected in most cases, regardless of the D/U ratio.
  • Page 57 GEX-P900DAB - What is SFN? Single Frequency Network (SFN) functions in the same way as with Network Follow (NF) of RDS. The principle of SFN uses the advantage of DAB that signals can be received for multipath having delay within the time of guide interval.
  • Page 58 GEX-P900DAB - Broadcasting Content DAB can be considered as a system that can transmit the conventional seven broadcasting stations using a single broadcasting wave. New styles of broadcasting can be offered by replacing the content of broadcasting in audio sig- nals with data.
