6. On Spectrally Efficient Continuous Phase Modulation
Sammanfattning : Spectrally efficient partial response continuous phase modulation (CPM)for wireless links is considered. Continuous phase modulation defines constantenvelope phase codes, which are advantageous when using non-linear amplifiers. LÄS MER
7. Development of Energy-based Damage and Plasticity Models for Asphalt Concrete Mixtures
Sammanfattning : Characterizing the full range of damage and plastic behaviour of asphalt mixtures under varying strain-rates and stress states is a complex and challenging task. One reason for this is partly due to the strain rate and temperature dependent nature of the material as well as the variation in the properties of the constituent materials that make up the composite asphalt mixture.

8. Some concatenated and iterative decoding approaches for continuous phase modulation
Sammanfattning : Several concatenated and iterative decoding approaches are used toimprove the power efficiency of continuous phase modulation (CPM).First a symbol interleaver is used for serially concatenated CPM(SCCPM). Convergence of iterative decoding for this scheme can beearlier (lower SNR: Signal-to-Noise-Ratio) compared to bitinterleaved SCCPM. LÄS MER
9. Serially Concatenated Space-Time Coded Continuous Phase Modulation
Sammanfattning : Certain problems associated with reliable digital wireless communication over a frequency-flat slow Rayleigh fadingchannel are treated, when the transmitted signal is modulated using continuous phase modulation (CPM) due to the desirable properties of CPM. The primary focus of attention is on detection strategies, and the thesis proposes iterative detection algorithms for CPM signals transmitted over frequency-flat slow Rayleigh fading channels.

10. Developing IPM tools for greenhouse cucumber production in Sweden – a participatory action research approach : control of the European tarnished plant bug and cucurbit powdery mildew
Sammanfattning : Two of the most important plant protection problems in Swedish cucumber production are the European Tarnished Plant Bug (ETPB), and Cucurbit Powdery mildew (CPM). The control of the ETPB relies on Imidacloprid, a pesticide, which breaks down slowly and is harmful to beneficial insects. LÄS MER
