Switched-Device Power Amplier using Bias Control

In this work, a switched-device power amplier using bias control is designed and realized. The PA operates at a frequency of 100MHz. Test results show that the PA achieves a PAE of 63% at −6dB power back-off and 60% at the peak output power of 40dBm. First, an overview of the state-of-the-art PA technology and performance in high PAPR...

Peak-to-Average Power Ratio Reduction Techniques for Wavelet Packet Modulation

Wavelet Packet Modulation (WPM) is a novel multicarrier modulation technique and a promising alternative to the well established Orthogonal Frequency Division Multiplexing (OFDM). WPM has been shown to be an efficient technique with interesting features like adaptation and flexibility and improved characteristics in comparison to OFDM. A major...
