Digital precompensation complementary to post equalization increases the DSP compensation envelope. Implementable parallel least square of nonlinear bandlimited channel, asymmetric imbalance predistortion of MZM impairments, and quantization noise preshaping minimizing DAC resolution requirement are presented.
