Write a matlab program to simulate 2pam baseband digital

Question

Problem - Write a Matlab program to simulate 2PAM baseband digital transmitter with truncated Sine pulse. The 2PAM signal corresponds to

X(t) = _i=0∑^N-1Ad_ip(t - iT_s)                                                                  (1)

where A is the signal amplitude, d_i is the i^th data symbol, p(t) is the pulse shape, and T_s is the symbol duration.

Please use a truncated sine pulse g(t) = sine(1/T_s) with five sidelobes on the left and five sidelobes on the right as the pulse shape for the 2PAM transmitter.

Procedure:

(1) input a character string from the keyboard;

(2) convert the characters into their ASCII codes (7 bits per character);

(3) create a 2PAM signal of these information bits with symbol duration T_s and truncated sine pulse;

(4) plot the 2PAM signal;

(5) plot the spectrum of this 2PAM signal.

In your project report, please include all Matlab programs (as appendix), plots and your discussion.
