Abstract

[The structure of a Digital Phase-Locked Loop (DPLL)-based systems for dealing with Nakagami-m fading is proposed in this chapter. The emphasis of the work is the implementation of the essential components of a DPLL for better reception of signals with certain modulation transmitted through Nakagami-m channels. A sixth order polynomial fitting algorithm for better phase-frequency detection has been implemented, which has helped to attain optimum performance of DPLL. The results of simulation of the proposed DPLL with Nakagami-m fading and QPSK modulation shows that the proposed method provides better performance than existing systems of similar type.]
