Query: PAPR Reduction of FBMC Signals Based on Uniform and Linear PDF
  Companding Schemes   In this paper, two new companders are designed to reduce the ratio of peak to
average power (PAPR) experienced by filter bank multicarrier (FBMC) signals.
Specifically, the compander basic model is generalized, which alter the
distributed FBMC signal amplitude peak. The proposed companders design approach
provides better performance in terms of reducing the PAPR, Bit Error Rate (BER)
and phase error degradation over the previously existing compander schemes.
Many PAPR reduction approaches, such as the Mu-law companding technique, are
also available. It results in the formation of spectrum side lobes, although
the proposed techniques result in a spectrum with fewer side lobes. The
theoretical analysis of linear compander and expander transform for a few
specific parameters are derived and analyzed. The suggested linear companding
technique is analytically analysed using simulations to show that it
efficiently decreases the high peaks in the FBMC system. Keywords- BER, CCDF,
Compander, FBMC, OQAM, PAPR, PSD.
