Abstract :
It is shown that the capacity of the AWGN channel can be approached via a multilevel coding scheme with the output of each encoder mapped into an independent signal constellation. No active shaping is required in this scheme, regardless of the signal-to-noise ratio. Moreover, shifted linear codes can be used
