We propose an equal length level conversion scheme to convert δ-σ modulation (DSM) output from 6-level to 4-level with approximately equivalent entropy. Compared to 4-level DSM systems, our proposed scheme achieves 11.6-dB gain in wireless signal SNR and 3.0-dB enhancement in received optical power sensitivity.
