Abstract
In this paper, performances of the extended QRD-RLS equalizer is analyzed. Since the extended QRD-RLS equalizer is efficiently implemented by systolic array architecture, we analyze performances of this structure with signals of different lengths. By multiplying the frequency responses of the unknown channel and proposed equalizer, we observed the flatness of the overall system function. Through the simulation, it is shown that the performance of the extended QRD-RLS equalizer is remarkably increased with input signals of length 16.
