System and method for huffman shaping in a data communication system
First Claim
Patent Images
1. A communication device, comprising:
- a transmitter and a receiver, the transmitter comprising a scrambler and a shaper,wherein data is input into the transmitter,wherein the scrambler scrambles the inputted data,wherein the shaper accumulates the scrambled data,wherein the accumulated data forms Huffman codewords,wherein the shaper maps the formed Huffman codewords into modulation symbols, andwherein the transmitter transmits the modulation symbols at a constant rate.

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.
