Power amplifiers are key elements in the modern communication systems. They are used to generate the required power and amplify the signal to be transmitted. Linear and efficient amplifiers are needed in most of modern wireless systems. However, either linearity or efficiency will be compromised during amplifier design procedure. In order to meet these two requirement at the same time, linearisers are usually applied on the efficient but nonlinear amplifiers. This dissertation presents a study of a novel linearisation technique, based on the minimal control synthesis (MCS) algorithm. The objective of this work is to demonstrate the feasibility of this new linearisation approach. The aim is achieved by the simulation and implementation results. The MCS-based lineariser can be implemented on their own. Alternatively, the adaptive controllers can be retrofitted to existing, more conventional control schemes, e.g. pre-distortion lineariser and Cartesian feedback lineariser.
