A New Channel Coding Technique to Approach the Channel Capacity

Abstract

After Shannon’s 1948 channel coding theorem, we have witnessed many channel coding techniques developed to achieve the Shannon limit. A wide range of channel codes is available with different complexity levels and error correction performance. Many powerful coding schemes have been deployed in the power-limited Additive White Gaussian Noise (AWGN) channel. However, it seems like we have arrived at an end of advancement path, for most of the existing channel codes. This article introduces a new coding technique that can either be used as the last coding stage of concatenated coding scheme or in parallel configuration with other powerful channel codes to achieve reliable error performance with moderately complex decoding. We will go through an example to understand the overall approach of the proposed coding technique, and finally we will look at some simulation results over an AWGN channel to demonstrate its potential.
