DAB, digital audio broadcasting or digital radio, is a digital broadcasting system for sound broadcasting in the VHF and L bands. Common frequency networks are possible. DAB is standardized by ETSI as EN 300 401.
COFDM (coded orthogonal frequency division multiplex). COFDM systems use OFDM modulation with forward error correction. Individual carriers are QPSK modulated (quadrature phase shift keying). The guard intervals do not show any carrier drop.
