Linearization and Approximation01:26

Linearization and Approximation

Linearization is a mathematical technique used to approximate complex, nonlinear functions with simpler linear models in the vicinity of a chosen reference point. The method is based on the idea that, although a function may be difficult to evaluate exactly, its behavior near a specific input value can often be closely approximated by the tangent line at that point. This approach is particularly useful when small deviations from a known value are involved.Consider the square root function, for...

Area of Science:

  • Photonics
  • Signal Processing
  • Electrical Engineering

Background:

  • Analog optical links often suffer from dynamic distortions that degrade signal quality.
  • Conventional linearization methods require excessive analog bandwidth, limiting their applicability.
  • Efficient suppression of intermodulation distortions is crucial for wideband signal transmission.

Purpose of the Study:

  • To present a novel digital postprocessing linearization technique for analog optical links.
  • To efficiently suppress dynamic distortions in wideband signals.
  • To achieve a high spurious-free dynamic range over a broad signal bandwidth.

Main Methods:

  • A digital postprocessing linearization technique is employed.
  • Undesired distortions are regenerated from the captured output signal.
  • Regenerated distortions are subtracted from the distorted digitized signal.

Main Results:

  • Achieved up to 35 dB suppression of intermodulation distortions over multiple octaves of signal bandwidth.
  • Demonstrated a record spurious-free dynamic range of 120 dB·Hz(2/3) over a 6 GHz electrical signal bandwidth.
  • The technique does not require excessive analog bandwidth for digital correction.

Conclusions:

  • The presented digital broadband linearization technique effectively suppresses dynamic distortions in analog optical links.
  • This method offers a significant advancement over conventional linearization approaches.
  • The technique is applicable to other nonlinear dynamic systems beyond optical links.
