Abstract
In one embodiment, the present invention comprises demultiplexing a bit stream into a first block and a second block, convolutionally coding the first block and block coding the second block. The invention further comprises applying the block coded second block to a function module to apply one of a plurality of different functions to form a third block at an output of the module and mapping the convolutionally coded first block and the third block to a modulation constellation for transmission, the mapping resulting in different constellation points depending on the applied function.
