Re: Dud DAB
DAB & DAB+ services all use punctured convolutional coding in transmission. For MP2 DAB services Unequal Error Correction is normally used, which applies an appropriate puncture level to each part of the audio frame so that failure occurs across the frame at the same time. AAC DAB+ services can’t use UEP because the frame format is different, so they need extra RS protection to fail at a similar BER to MP2 DAB services.
