I have taken random data using randn and then psk modulated it...But i get error.
M=1024;
m=4;
msg1=randn(M,1,m);
msg2=randn(M,1,m);
msg=vertcat(msg1,msg2);
% QPSK modulation
qpsk_modulated_data1=pskmod(msg1,m);
qpsk_modulated_data2=pskmod(msg2,m);

You want to generate your data using randi() like this:
M = 4;
msg1 = randi([0, 3],1024,1);
qpsk_modulated_data1 = pskmod(msg1,M);

You realize that
randn(M,1,m)
is not going to produce integers in the range [0, m-1]? Maybe you want
doc randi
