Write me a matlab code that takes an image as an input and sends it over a nakagami-m fading channel in an OFDM wireless communication link. After demodulation denoising will be performed to give the final output

# Read image
image = cv2.imread('img.jpg',0)

# Modulate image
mod_img = modulation(image)

# Send modulated image
send_img = channel(mod_img)

# Demodulate image
demod_img = demodulation(send_img)

# Denoise image
denoise_img = denoise(demod_img)

# Show image
cv2.imshow('image', denoise_img)
