Carrier Frequency Offset impairment in MATLAB
This section of MATLAB source code covers Carrier Frequency Offset impairment and Carrier Frequency Offset effect on constellation diagram using matlab code.
Part A and PART C of the matlab code is same as mentioned on AWGN page.
Source code -PART B
foff=(foff)/20e6; % 20MHz is the Bandwidth of the system
figure;plot(real(map_out_foff),imag(map_out_foff),'r+');title('constellation with Frequency offset');
Input and output constellation diagram
