Abstract
Techniques for puncturing symbols in a communications system. S symbols are received for a frame having a capacity of N symbols, with S being greater than N. P symbols need to be punctured so that remaining symbols fit into the frame. A number of puncture distances, Dthrough DN, are computed based on S and P. A particular number of symbol punctures is determined for each computed puncture distance. Pthrough PN symbol punctures are then performed at the distances of Dthrough DN, respectively. For a more even distribution of the symbol punctures, each of the distances Dthrough DN can be selected to be greater than or equal to a minimum puncture distance Dmin defined as Dmin=└S/P┘, where └ ┘ denotes a floor operator. The symbol punctures at each computed distance can be performed together or distributed with symbol punctures at other distances.
