It is mostly observed in mobile communication. In the first approach, the structure of a Digital phase locked loop (DPLL) based on Zero Crossing (ZC) algorithm is proposed. In a modified form, the structure of a DPLL based systems for dealing with Nakagami-m fading based on Least Square Polynomial Fitting Filter is proposed, which operates at moderate sampling frequencies. 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 is discussed in detail which shows that the proposed method provides better performance than existing systems of similar type.Signals and Communication Technology,1860-4862Electrical engineeringElectronicsMicroelectronicsComputer networksCommunications Engineering, Networkshttps://scigraph.springernature.com/ontologies/product-market-codes/T24035Electronics and Microelectronics, Instrumentationhttps://scigraph.springernature.com/ontologies/product-market-codes/T24027Computer Communication Networkshttps://scigraph.springernature.com/ontologies/product-market-codes/I13022Electrical engineering.Electronics.Microelectronics.Computer networks.Communications Engineering, Networks.Electronics and Microelectronics, Instrumentation.Computer Communication Networks.621.3822Purkayastha Basab Bijoyauthttp://id.loc.gov/vocabulary/relators/aut721061Sarma Kandarpa Kumarauthttp://id.loc.gov/vocabulary/relators/autMiAaPQMiAaPQMiAaPQBOOK9910299683403321A Digital Phase Locked Loop based Signal and Symbol Recovery System for Wireless Channel2527370UNINA
