A Platform for Adaptive Equalization Prototyping

Ž. Nakutis


Hardware prototyping platform for the adaptive equalizer investigation is presented in the paper. The platform consist the equalizer, communication channel, excitation and signal acquisition means that are mapped to two Digital Spectrum Starter Kits based on Texas Instruments DSP and PC sound card. Simulink models of the equalizer, communication channel and excitation generator are compiled and executed by the processors of the DSK boards. The ability of the implemented equalizer to reconstruct shape of the excitation pulses distorted by the communication channel was demonstrated. The proposed adaptive equalization prototyping platform can be used as a supplement to simulation in education. Ill. 6, bibl. 10 (in English; summaries in English, Russian and Lithuanian).
