Acronym for "Digital Audio Broadcast". Especially for mobile reception (``car radio'') the quality of the received audio program suffers because of noise and signal drop-outs. These problems are solved by DAB by incorperating the following schemes (among others): Forward Error-Correction (FEC), based on convolutional codes, Orthogonal Frequency Division Multiplexing (OFDM) and Redistribution of the data bits over some time interval (time interleaving).
