poly_p3V3.m

k=1; fc = 180e6; fs = 240e6; tp = 6e-6; N= fs*tp; t=0:1/fs:((1/fs)*1440); for n = 1:1:1440; p3(k)= pi*((k-1)^2)/(N) sig(n)= exp(1j*(2*pi*fc*t(n)+(p3(k)))); if (rem(n,48)==0) k=k+1; end; end;

tx= zeros(1,5000); rx= zeros(1,5000); tx(1:1440)=sig; rx(1463:1440+1462)=sig; figure(1); plot((1:5000)/fs,tx); figure(1);hold on; plot((1:5000)/fs,rx,'r'); fft_tx=fftshift(fft(tx)); figure(3) plot(-0.5+1/N:1/N:0.5,abs(fft_tx(1:N))); fft_rx = fftshift(fft(rx)); figure(4) plot(-0.5+1/N:1/N:0.5,abs(fft_rx(1:N)));

out_mat     = ifft((fft_rx).*conj(fft_tx)); 
figure(5) 
plot(1/fs*(1:5000), abs(out_mat)/max(abs(out_mat)));
figure(5);hold on;plot((1463/fs),1,'r*');

HDL Coder can take MATLAB code and convert it into Verilog. However, you need to consider your code from the perspective of what tasks can be done in hardware. Two simple function calls in your code that cannot be performed in hardware are the figure() call and the plot() call.

You will need to figure out how to separate your code into design and stimulus/response portions. The design portion can be developed to be convertible to HDL code.
