    Abstract :

    Wireless spectrum is considered a limited and valuable communications resource as it influences productivity, security and our daily lives. One of the driving strengths of QPSK using Gaussian method is the Signal-to-Noise Ratio (SNR) estimation and feedback channel for adaptation. Sudden time varying channel degrading effects sometimes require the transmission link to react appropriately so it can minimize the Bit Error Rate (BER). Thus, the objective of the thesis introduces a QPSK modulated scheme which utilizes a simple moments based SNR estimator for spectral and quality improvement for the wireless channel. Results of the our proposed method shows that Bit error rate in our proposed QPSK using Gaussian method modulated channel decreases as compared to the QPSK modulated channel.
