1. Joint CFR and DPD optimization for 5G Digital Front Ends
University essay from Lunds universitet/Matematik LTHAbstract : This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and DPD algorithms.

3. Current-Mode Class D Power Amplifier for 2.4GHz Wi-Fi
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Modern wireless communication techniques employed in the Wi-Fi® protocol, such as orthogonal frequency-division multiplexing exhibit analogue signals with high peak-to-average power ratio. Therefore, power amplifiers for Wi-Fi suffer from low efficiency when operating in back-off mode, away from their maximum efficiency at peak power. READ MORE

5. Digital Microwave Control of Superconducting Qubits
University essay from KTH/Tillämpad fysikAbstract : We manipulate two superconducting qubits using digital microwave electronics. Starting fromtheir characterization, we develop a real-time reset scheme and implement the iSwap gate. Thequbits’ parameters are obtained using standard single-qubit characterization techniques, such asRabi and Ramsey oscillations and frequency sweep of the resonators. READ MORE
