[QUOTE="ktan, post: 2402761, member: 676514"] Hey everybody, I have a project in Matlab (and unfortunately they never taught me how to use it...funny isn't it?) and I've been trying to find tutorials all over the internet to understand this program. The issue is that I have generate a BMP file with 256 by 256, 8 bits, GREY scale (no color) 1. I have to design my own modulation and demodulation models 2. Show the time signal, eye diagram and constellation for no noise, SNR=0dB, SNR=5dB, and SNR=10dB 3. Calculate the Bit error rate vs. SNR curves for BPSK. Compare that with the theoretical curve 4. Transmit images, BPSK only a) alignment for both timing and data b) PSNR vs. SNR curves c) print images for SNR=0dB, SNR=2.5dB, SNR=5dB 5. Timing errors a)oversample 16 times in matlab b)1/16, 2/16, then what is BER vs. SNR and what is PSNR vs. SNR Now obviously I don't want you guys to do the work for me, but I'd sure like some direction on how to approach this. If you could point me to any resources that could help me understand or give any direct advice, that would great. I never learned how to use MATLAB and I'm having a hard time finding resources.
