Abstract
In a digital audio broadcast receiver a digital audio transmission signal is supplied to a demodulator which provides demodulation samples. The demodulation samples are de-interleaved in a first section of a de-interleaving memory. After having been de-interleaved, demodulation samples are transferred to a second section of the de-interleaving memory. This transfer is effectuated in bursts via a relatively small buffer which stores the bursts. The second section of the de-interleaving memory effectively constitutes a relatively large buffer. De-interleaved demodulations samples are regularly read from the second section and supplied as a regular stream to a Viterbi decoder by means of a relatively small first-in first-out register.
