Probabilistic Shaping Techniques for High-Performance Coherent Optical Transceivers:

Hueda's patented method and structure for probabilistic shaping and compensation techniques in coherent optical receivers have garnered considerable attention. By implementing distribution matcher encoders and decoders, Hueda's techniques offer an innovative alternative to traditional arithmetic coding, which often relies on resource-intensive multiplication functions. Moreover, these probabilistic shaping techniques seamlessly integrate with LDPC codes through reverse concatenation techniques, further enhancing the system's overall efficiency and performance.

Tap Centerer Method and Structure for Coherent Optical Receivers:

Another significant breakthrough from Hueda is related to tap centering in coherent optical receiver devices. In the context of dual-polarization optical coherent receivers that employ frequency domain (FD) adaptive equalizers, computing the center of gravity (CG) of the filter coefficients poses a challenge. Hueda's patented method estimates the CG directly from the FD equalizer taps, allowing for efficient compensation of convergence errors based on the estimated CG. This innovative approach strikes an optimal balance between accuracy and complexity, offering a promising solution for time-domain adaptive equalizer convergence evaluation.
