clc;clear all;close all;
input=[1 1 0 1 0 0 1 0 ]; %input bit
M=4;
Nsc=148;
N = 2;
X = bin2dec(reshape(sprintf('%u',input),N,[]).'); %bin2dec conversion
y=qammod(X,M);
scatterplot(y); %QAM modulation
This is my code. I don't know how to do subcarrier mapping and finally I have to generate IFFT signal after mapping. Can someone help me with this?
