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=input('Enter Frequency offset:');%= 10e3; % Hz
foff=(foff)/20e6; % 20MHz is the Bandwidth of the system
map_out_foff=frequency_offset(mapper_out,foff);
figure;plot(real(map_out_foff),imag(map_out_foff),'r+');title('constellation with Frequency offset');
foff=(foff)/20e6; % 20MHz is the Bandwidth of the system
