Speaker Recognition is one of the most useful biometric recognition techniques in this world where insecurity is a major concern. This book introduces a method for speaker recognition on the basis of the individual information included in speech waves. This can mainly be divided into two parts speaker identification and speaker verification. Speaker Identification find outs which speaker has uttered the given speech and Speaker Verification verifies their identity. Speaker recognition technology is the most potential technology to create new services that will make our everyday lives more...

Orthogonal Frequency Division Multiplexing (OFDM) is a promising technology in wireless communication. High Peak-to-Average Power Ratio (PAPR) is one of the challenging issues of OFDM systems. High PAPR forces the High Power Amplifier (HPA) to operate in its linear region with wide dynamic range, where the power efficiency is very poor. This book gives an overview of different PAPR reduction techniques. And deals in detail with the efficient use of Selected Mapping (SLM) and Partial Transmit Sequence (PTS)technique to reduce high PAPR in OFDM systems.
