There are two files in the zip folder. bpsk_spread.m and jakesmodel.m

Steps for simulation:

1] Run jakesmodel.m first

2] Then run bpsk_spread.m .

3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented

4] The resulting performance is stored in BER_awgn.

5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file.

6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable.

7] Run the simulation.



To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray
