8.1 Introduction / Classification
of Frequency Control Systems
In this chapter we are concerned with frequency estimation. We could have studied this problem earlier in Chapter 5 by including an additional parameter Q in the set 8 = (0, E, a}. The main reason why we choose to include a separate chapter is that for a sizeable frequency offset St we must first compensate this frequency offset before the other parameters (0, E, a} can be estimated. This implies that frequency offset estimation algorithms must work independently of the values of the other parameters. The operation of the algorithms is nondata...
