DSSS Plotting

I have a QPSK signal (amplitude samples) that I've spread using DSSS. The PSD of the DSSS spread signal should be spread in frequency and the power should go down. When I plot the frequency response of the DSSS signal, it looks spread but has not attenuated. I use the function {plot (20*log(fft(DSSS_time_domain_signal)))} to plot the DSSS frequency version of the signal. Is there something Im not considering when plotting?
