cdma

how to perform implementation of cdma using matlab code,

steps involved:

 1)get the input binary data (b(t))
 2)generate PN sequence using LFSR (c(t))
 3)perform y(t)=b(t).c(t) [plot y(t) b(t) c(t)]
 4)modulate y(t)
 5)demodulate to get the original input data. then display frequency,time of input data signal, spreaded signal and the modulated signal
