USE MATLAB FOR CODING

1. Randomly generate a vector whose entries are 4-QAM symbols with length N = 5.000 symbols. In order to generate this vector, first you need to generate a vector with entries are sampled from a discrete random variable, which can take values of {0,1,2,3} with equal prior probability. Then, you modulate each element of the vector in order to obtain 4-QAM symbols. In your simulations, the average energy of a symbol should be Es = 1. Obtain the scatterplot of the generated symbols
