Sample interview questions: How have you utilized equalization techniques in your digital communications signal processing work?
Sample answer:
- Adaptive Equalization:
-
Used adaptive algorithms, such as Least Mean Square (LMS) or Recursive Least Squares (RLS), to automatically adjust the equalizer coefficients in response to channel variations.
-
Decision Feedback Equalization (DFE):
-
Incorporated DFE to mitigate intersymbol interference (ISI) by utilizing past decisions to estimate and cancel the ISI.
-
Fractionally Spaced Equalization (FSE):
-
Employed FSE to achieve equalization at a higher sampling rate than the symbol rate, resulting in improved performance in channels with severe ISI.
-
Blind Equalization:
-
Implemented blind equalization techniques, such as Constant Modulus Algo… Read full answer
