Recent technology advance on transmitter-side DSP such as digital pulse-shaping, pre-equalization and digital nonlinear compensation has also been discussed.
Propose an overlap structure equalization algorithm for the pre-echo channel, which can weaken the dependence on feedforward equalizer, enhance the performance and reduce the complexity.
