An Enhanced Companding Algorithm for Universal Filtered Multi-Carrier System
ETRI JournalThis paper proposes a new companding scheme called three μ-law compand-ing to reduce the peak-to-average power ratio (PAPR) in a universal filtered multicarrier system. The proposed scheme is more flexible and provides better PAPR reduction and bit error

Simplified technique for syllabic companding inlog-domain filters
Electronics Letters, 2000 It is shown that when syllabic companding is applied to log-domain filters using dynamic biasing, their large signal linearity can be exploited to eliminate the state variable compensation circuit. Owing to its simplicity, the proposed technique has several advantages over previous approaches.

Simple Compression Algorithm for Memoryless Laplacian Source Based on the Optimal Companding Technique [PDF]
Informatica, 2009 This paper has two achievements. The first aim of this paper is optimization of the lossy compression coder realized as companding quantizer with optimal compression law. This optimization is achieved by optimizing maximal amplitude for that optimal companding quantizer for Laplacian source.
