Nonlinear Signal Processing for Efficient Wireless Transmitters

PhD Student 

Modern spectral efficient modulation formats like OFDM generate time-domain waveforms with high peak-to-average power ratio and require highly linear amplification. With traditional transmitter architectures, this leads to low power efficiency. The aim of this thesis is to study system design and signal processing methods, which can be used to improve the power efficiency, either by digital enhancement of analog/RF circuits or by fully digital transmitter architectures. These digital-centric methods are especially suited for CMOS implementation, since they take advantage of the scalability of digital circuits.
