When signal-to-noise ratio is 0dB , 8dB , 16 dB , plot the noisy constellation points for 16-QAM and QPSK .You need to have 6 figures ( 3 for QPSK , where one corresponds to SNR value , 3 for 16-QAM ) Matlab code is necessary and figures must be labelled .
Hi, we have experienced team of Engineers. We have understood that you need Communication system expert. We offer our services for this project. We have made many Communication System based projects using Matlab as follows;
• Comparison between theoretical and simulation of 4-PAM.
• Plot input and output time sequences and their fourier transform sequences of LTI system.
• Comparison of Fourier transform of signals having different sampling rates.
• Generating binary messages using Filtering and Fourier Series.
• Applying the 3-bit uniform Quantization on the discrete time speech signal.
• QPSK modulation of the quantized speech signal.
• Investigating the effect of noise on QPSK symbols of the quantized speech signal.
• Oversampling/ Interpolation of the QPSK modulated quantized speech signal.
• Design of Root Raised Cosine filter for the oversampled QPSK data.
• Automatic and Manual Home Automation using Power Line Communication with display of Power consumption through each node on LCD and GUI to display status of entire loads.
We ensure you to complete your project efficiently in time.
