| Abstract: | A model of a linear digital communication system is introduced and adaptive equalization in general is explained. A five-tap transversal equalizer is designed, breadboarded and tested in a 60 Mb/s burst mode modem in a quasi-linear and a non-linear channel under the following configurations: - 1 Parabolic, linear and combination of parabolic and linear delay distortions were inserted after the non-linearity (TWTA).
- 2 Case 1 was repeated with distortions inserted before the non-linearity.
When parabolic distortion is added before the non-linearity improvements in the BER are significant. |
