Abstract
A system and method for convolutionally encoding a stream of bits are disclosed. An embodiment of the present invention provides improved communication system performance in comparison to existing convolutional coding, such as that proposed for use in systems employing multi-band, orthogonal frequency division multiplexed signaling. A generator polynomial having a native code rate R=1/3 may be used in combination with puncturing patterns supporting multiple codes rates. The resulting convolutional encoder exhibits improved performance at all code rates, and has no known disadvantages.
