Abstract

The modified structure of a Least Square Polynomial Fitting Filter-based Digital Phase-Locked Loop-based systems for dealing with Nakagami-m fading is proposed here. 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 Least Square Polynomial Fitting (LSPF) block and Roots Approximator (RA) for better phase-frequency detection has been implemented as a replacement of Phase Frequency Detector (PFD) and Loop Filter (LF) of a traditional DPLL, which has helped to attain optimum performance of DPLL. The results of simulation of the proposed DPLL with Nakagami-m fading and QPSK modulation show that the proposed method provides better performance than existing systems of similar type.
