Paper Abstract

We propose and verify through computer simulations the use of a precoding technique to eliminate the nonlinear distortions in an M-QAM channel which is transported along with multiple AM-VSB channels by a laser diode. We show that the precoding technique can completely remove the clipping- induced bit-error-rate floor at a cost of a 3 dB signal-to- noise ratio reduction.
