摘要：

The authors report the empirical performance of Gallager's low density parity check codes on Gaussian channels. It is shown that performance substantially better than that of standard convolutional and concatenated codes can be achieved; indeed the performance is almost as dose to the Shannon limit as that of Turbo codes.
