This group-delay equalizer can follow any type of HTS microstrip filter in order to reduce phase distortion, enhance group-delay performance, and improve communication quality.
To minimize the frequency and phase distortion in a DTV transmitter in order to achieve best VSB frequency performance, a pre equalizer can be inserted into the modulator.
It is proved that UV channel is a minimum phase system and can use blind equalizer. Ber is not sensitive to the step size and tap number for CMA blind equalizer.
