Abstract: Mobile communications have seminal importance in telecommunication systems. Thrust challenges in optimization area like capacity to scale up in channels, coverage area and integration of newer techniques with minimum design efforts are targeted in this work. This article proposes a novel technique of configuring the present decoder with Euclidian distance polar-code decoding method at low hardware efforts. The Taguchi optimization technique based on orthogonal array method for polar-code is employed to carry out an experimental design to achieve parameter optimization. This method helps to cram interaction between process parameters. Taguchi optimization analysis of polarization effect of polar code and 8 PSK higher modulations resulted into an increase in channel utilization and bandwidth. The experimentation results proved a low SNR of 9.8 dB and efficient channel utilization of 2.9956 bits/Hz for desired BER of 10- 4, reducing network congestion by 1.5 times. At the same time, yield in bandwidth has sunk from 25 KHz to 16.66 KHz by paying minimum penalty of 1.496 dB in required SNR.
