First Claim
Patent Images
1. In a communication system, a method of communicating data comprising:
- accepting data from a source of user data;
accumulating the data until a Huffman codeword is recognized;
mapping the Huffman codeword into a channel symbol; and
applying the channel symbol to an input of a channel.

Abstract
In a communication system, Huffman coding techniques are used to obtain shaping gains for an improvement in data transmission rates. More particularly, a novel method of Huffman shaping is described that achieves a shaping gain of greater than 1 dB. The shaping gain results in a higher data rate transmission in a communication system where transmitted power is constrained.
