STOKES-SPACE FORMALISM FOR BRAGG SCATTERING IN A FIBER

  • Mckinstrie C.

Optical frequency conversion by four-wave mixing (Bragg scattering) in a fiber is considered. The evolution of this process can be modeled using the signal and idler amplitudes, which are complex, or Stokes-like parameters, which are real. The Stokes-space formalism allows one to visualize power and phase information simultaneously, and produces ...

SIGNAL PROCESSING ENHANCING OBJECTIVE EVALUATION OF SPEECH QUALITY ALGORITHM: CURRENT EFFORTS, LIMITATIONS AND FUTURE DIRECTIONS

  • Lee M.
  • Lee W.
  • Mcgowan J

We discuss a performance improvement over the current state-of-the-art objective speech quality assessment algorithm by means of a parameter study. The state-of-the-art algorithm computes a certain measure of disturbances surface, and applies a cognitive model to map the computed value to the scale used mean opinion score (MOS). We note ...

NON-STATIONARY MULTIPLE-ANTENNA INTERFERENCE CANCELLATION FOR UNSYNCHRONIZED OFDM SYSTEMS WITH DISTRIBUTED TRAININGSTAR, OPEN

  • Kuzminskiy A.

Adaptive interference cancellation is addressed in an asynchronous orthogonal frequency-division multiplexing (OFDM) system with a frame containing a number of temporally distributed pilot symbols, e.g., as in the IEEE 802.16-2004 standard. Non-stationary symbol-by-symbol switching technique is proposed that is based on banks of the second-order statistics semi-blind solutions with on-line ...
