On the selection of the best companding technique for PAPR reduction in OFDM systems
Orthogonal frequency division multiplexing (OFDM) is used in high data rate applications due to its ability to cope with frequency-selective channels. However, OFDM suffers from the high peak-to-average power ratio (PAPR) problem, which reduces the power

Companding technique for AM-SCM-PCMlightwave CATV systems
The companding technique has been shown theoretically to be effective for improving the fundamental CNR limit of AM-SCM-PCM lightwave CATV systems. For an 8 bit and 10 bit system, the improvement could be 3 and 4 dB, respectively, by use of erf-type companding, the corresponding CNR limits being raised to 44.8 and 56.8 dB, respectively.

Comparison of Companding based PAPR Techniques for OFDM Systems [PDF]
LTE has utilized the OFDMA for the downlink which provides spectrum flexibility, inherent resistance to Inter symbol Interference (ISI) and many more. However 3GPP LTE systems suffer from a very common problem known as Peak to Average Power ratio. The present paper tried to discuss the companding based techniques for single user OFDMA systems.

Simplified technique for syllabic companding inlog-domain filters
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.
