A simple and effective method for linearization of power amplifiers (PAs) is proposed. The
method is based on the second harmonic injection into the input of the PA. The second …

One of the effective methods used for reducing peak‐to‐average power ratio (PAPR) in
orthogonal frequency division multiplexing (OFDM) systems is selected map** (SLM). In …

The application of digital predistortion in base band signal is an extended method of
amplifier linearization to reduce the Adjacent Channel Interference (ACI) in those systems in …

In this paper, the effects of peak‐to‐average power ratio reduction in nonlinear power
amplifiers (PAs) by considering memory effects and of digital predistortion are investigated …

In this paper the peak to average power ratio (PAPR) reduction and digital predistortion
effects in orthogonal frequency division multiplexing (OFDM) systems are investigated. By …

Radio frequency (RF) power amplifiers (PAs) are the most power consuming and inefficient
devices in RF transceiver systems and are often integrated with performance enhancement …

Power amplifiers are essential components in communication systems and are inherently
nonlinear. The nonlinearity creates spectral growth beyond the signal bandwidth, which …

Peak-to-average power ratio (PAPR) is one of the main drawbacks in orthogonal frequency
division multiplexing (OFDM) systems. High PAPR forces the power amplifier to back off in …

In this paper a new partial transmit sequence (PTS) scheme called enhanced PTS (EPTS) is
introduced to reduce the peak-to-average power ratio (PAPR) in orthogonal frequency …

The article introduces an integrated hardware/software codesign and test platform for the
digital predistortion and power amplifier blocks of radiofrequency transceivers. The platform …
