System-level design of modern communication system usually follows the “specification approach” that is based on three main components; a set of specifications an algorithm that models the proposed system and a simulation tool. System-level design using this approach starts by setting up a list of specifications for the intended system and then developing an algorithm based on these specifications that achieves the desired performance criteria. A simulator is then used to evaluate the selected algorithm and to provide insight into which parameters of the algorithm need to be adapted in order to achieve the predefined performance criteria.

N ) is the n-dimensional Volterra kernel that can be symmetric without loss of generality and leads to a unique set of Volterra kernels. Other models for nonlinear systems with memory are discussed in Chapter 3. 2 PA Classes PA designs fall into a number of classes according to their biasing conditions. Different classes have different nonlinear characteristics and hence, different power efficiencies. The most common PA classes are Class A, B, AB, C, D, E and F, where Class A, B and AB being linear (with low power efficiency) whereas the others are nonlinear (with high power efficiency).

In wireless systems, the channel is simply the space through which the transmitted signal must propagate to reach the receiver. Therefore, the main task of the transmitter is to convert the signal to a form suitable for transmission through space. This process is executed through the RF stage of the transmitter where modulation, up conversion, amplification and transmission through an antenna take place. At the receiver side, the transmitted signal is first received by an RF stage of the receiver where signal reception through an antenna, amplification, down conversion and demodulation processes are executed.
