A method of digital audio broadcasting comprises the steps of providing a
plurality of bits of digital information to be transmitted, forward error
correcting the bits of digital information using a combination of
pragmatic trellis code modulation and complementary punctured code, and
transmitting the bits of digital information. The step of forward error
correcting the bits of digital information can comprise the steps of
representing the bits as independently coded in-phase and quadrature
signals, applying a first error correcting code to the in-phase signals,
and applying a second error correcting code to the quadrature signals.
The bits of digital information can be arranged in a plurality of
partitions of code, wherein first and second ones of the partitions do
not overlap, a third one of the partitions overlaps a first portion of
the first and second partitions, and a fourth one of the partitions
overlaps a second portion of the first and second partitions. Apparatus
for transmitting and receiving digital audio broadcasting signals in
accordance with the above method are also provided.
