Abstract:
1. A method of generating code words for symbol-based error correction coding of a channel having a non-uniform signal-to-noise ratio, the method comprising: accessing a signal-to-noise ratio value associated with each symbol in the channel, wherein a plurality of the symbols are non-uniform symbols, wherein the non-uniform symbols comprise portions of at least two sections of the channel, wherein the at least two sections of the channel have different signal-to-noise ratio values, and wherein the signal-to-noise ratio value of a particular non-uniform symbol is based on a weighted average of signal-to-noise ratio values of the portions of channel sections comprising the particular non-uniform symbol; grouping the symbols in the channel into sets, wherein the symbols are grouped into sets according to signal-to-noise ratio values associated with the symbols; partitioning each set into partitions based on a number of code words for the channel; and generating the code words by interleaving the partitions from the sets.
