1. 1. Development and Investigation of an Automated Temperature Calibration for Temperature Phosphors

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :Xin Xu; [2012]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : This thesis achieves a semi-automatic temperature calibration for thermographic phosphors. Thermocouple temperature information and phosphorescence decay curves are recorded synchronized and continuously while the oven temperature is ramped across the entire temperature range. LÄS MER

3. 2. IEEE 802.11n MIMO Modeling and Channel Estimation Implementation

   Master-uppsats, Institutionen för systemteknik; Tekniska högskolan

   Författare :Xin Xu; [2012]
   Nyckelord :Simulink; MIMO; OFDM; STBC; Beamforming; MMSE detector; channel estimation;

   Sammanfattning : With the increasing demand of higher data rate for telecommunication, the IEEE802.11n standard was constituted in 2009. Themost important character of the standard is MIMO-OFDM, which not only improves the throughput but also the spectrumefficiency and channel capacity. This report focuses on the physical layer IEEE802. LÄS MER
