High-Resolution Source Coding for Non-Difference Distortion Measures: Multidimensional Companding

, 1996
Entropy coded vector quantization is studied using high resolution multidimensional companding over a class of non-difference distortion measures. For distortion measures which are "locally quadratic" a rigorous derivation of the asymptotic ...

PAPR Reduction of Optical OFDM Systems with Exponential Companding Transform and Zero Padding

Optical wireless communication (OWC) is an alternative to radio frequency (RF)communication with a signi cantly larger and unregulated spectrum. In OWC systems, optical orthogonal frequency division multiplexing (O-OFDM) with intensity modulation and ...

Research on Companding Filters

, 2010
Two kinds of companding filters are presented in this dissertation. The first one is a square-root domain filter based on operational transconductance amplifier (OTA). This one is compact and simple.
