Abstract
The channel noise is the severely degraded the performance of communication system and that also limits the maximum data transmission rate. Hence, it is required to design a demodulator in a receiver which overcomes the effect of noise in the received signal, reconstructs un-corrupted information signal and improves data rate. In QPSK, noise effect the phase of the modulated signal and that causes error in the information signal. This study tackles this crucial issue in the field of communication systems by presenting a noise-free technique for QPSK demodulation. The proposed algorithm compares the received noisy signal with stored sampled values of ideal signal having SNR of 15dB to 35dB that detects the phase of the modulated signal and eventually it reconstructs noise free information signal. The algorithm’s performance is thoroughly evaluated, and thorough Bit Error Rate (BER) measurements at different Signal-to-Noise Ratios (SNRs) show how successful it is. The proposed QPSK Modem is validated using Open ROAD EDA tool with Sky water SKY130HD Process Design Kit (pdk) and found a maximum operating frequency of 533MHz.
