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.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9788132229391\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9788132220404\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9788132229391","offer_id":39440270393437,"sku":"9788132229391","price":106.99,"currency_code":"EUR","in_stock":true},{"title":"Hardcover - 9788132220404","offer_id":40591047032925,"sku":"9788132220404","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/95a90fa8-1717-4273-8d13-78fffef44b4b.jpg?v=1775109685","url":"https:\/\/shop.autorenwelt.de\/products\/a-digital-phase-locked-loop-based-signal-and-symbol-recovery-system-for-wireless-channel-von-basab-bijoy-purkayastha-kandarpa-kumar-sarma","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
