摘　　要：In spite of the rapid developments in communication technologies over the past few decades, which include attractive features offered by the presently used 3G/4G systems,让 continues to be a challenge to render adequate services with the exponential rise in the number of users and applications. However, efficient alternatives, including 5G methods, are being explored to mitigate this problem. Such systems also aspire to render sustained coverage with lesser constraints on power and Quality of Service (QoS). Today, versatile Digital Phase Locked Loop (DPLL) based packages find place as communication receivers. Of late, a Least Square Polynomial Fitting DPLL (LSPF-DPLL) with Modified Phase Resolving Numerically Controlled Oscillator (MPR-NCO), which demonstrates excellent time performance and maintains satisfactory error rates, was proposed. A Bose, Chaudhuri, and Hocquenghem (BCH) channel code assisted version of the MPR-NCO based LSPF-DPLL system is presented here. The proposed system exhibits better B让 Error Rate (BER), throughput, and baud rate levels over the previously proposed uncoded version.
