Abstract
A method for prioritizing protection in the symbol mapping of selected information includes the steps of supplying information bits and overhead bits. Interleaving the information bits and overhead bits to supply a plurality of interleaved data blocks. And selectively mapping the plurality of interleaved data blocks into a modulation symbol.
Claims10
In a wireless communications system, a method to prioritize protection in the symbol mapping of selected information, the method comprising:
- supplying information bits and overhead bits;,
- interleaving the information bits and overhead bits to supply a plurality of interleaved data blocks;
- selectively mapping the plurality of interleaved data blocks into a modulation symbol.
A wireless transmitter, comprising:
- an encoder having an output providing information bits and overhead bits;
- first and second code bit interleavers;
- a demultiplexer coupled to the output of the encoder for distributing the information and overhead bits provided at the output of the encoder to the first and second code bit interleavers as a plurality of interleaved data blocks;
- and
- a mapper coupled to the first and second code bit interleavers for mapping the plurality of interleaved data blocks into a modulation symbol.
