This thesis analyses how and why culture and geography influence the allocation and licensing of the radio frequency (RF) spectrum in different nations. Based on a broad comparative study of 235 countries, an inter-disciplinary approach is used to explore regulatory frameworks and attitudes toward risk. In addition, detailed case studies of the UK, France, the US and Ecuador provide deeper insights into the main contrasting regulatory styles. Three alternative sociological theories are used to analyse and explain the results for both the in-depth and broad brush studies. The Cultural Theory of Mary Douglas and co-workers is first used to categorise countries in terms of perceptual filters. The empirical findings indicate some countries to be apparently exceptional in their behaviour. Th...

The complexity requirements of future wireless communication systems now indeed demand a more general theoretically robust design methodology for nonlinear circuits, such as the power amplifiers. The present design methodology for nonlinear Radio Frequency components and circuits has become a key hindrance in the evaluation, development and testing of modern communication systems. The fundamental nature of this engineering challenge makes it highly unlikely to be addressed within the competitive Radio Frequency industry with short-term profitability, time to market and risk aversion considerations.The book, therefore, includes developing advanced waveform measurement setups, multi-tone measurement techniques, characterization and modelling of nonlinear distortion in microwave power transis...
