Power effiCienCy in wireless CommuniCations
thecompanding method is used in speech processing. Due to com-
panding, the quantization error for large signals is considerably large,
which degrades the BER performance of the system (Hosseini et al.,
2006). In Takyu et al. (2006), each symbol is divided into groups
of consecutive segments or clusters. Each cluster is multiplied by a
weight equal to the inverse of the largest instantaneous power within
the cluster. e receiver must guess the weight of each cluster, which
results in BER degradation (Vijayarangan and Sukanesh, 2009).
4.3.2 Distortionless-Based PAPR Reduction Methods
When distortionless-based methods are applied to the system to
reduce PAPR, no distortion is added; however, com
